KLM - WORST AIRLINE EVER

I've tried to submit this message to KLM twice now, but it is not receiving it, so I am posting it for you to reference.  Formatting is not working:

KLM has officially ruined my vacation. Have spent my 4 days in London on the phone about changing a one way ticket to Amsterdam 

• I called on 4/16 to see if I could change flight from original 4/18 one way from Heathrow to Amsterdam to 4/19 because I wanted an extra day in London. Agent advised that it was cheaper if I bought a RT ticket from LCY and just not use the return flight, so I booked it.

[4/16] I notified KLM Cares of my new flight, as I was applying for flying with Emotional Assistance Animal - KLM Cares replies that I am not allowed to take an animal out of LCY, so I call KLM back to change ticket to London Heathrow. I submit my new application [4/17 - Part 1] KLM Cares replies that I need to apply with London Heathrow and pay a change fee of £300+ before they can approve my application. I call Heathrow and they verify that I do NOT need to pay to fly a dog out of the country 

• KLM Cares then replies that it is only because I have a RT ticket. They also now say that I can fly out of LCY 
•  I call KLM to change ticket to one way from LCY to Amsterdam. The woman quotes me £68 and waives rebooking and penalty fee (even though I upgraded anyway so I was allowed changes) 

[4/17 Part 2] KLM then calls me and says there is confusion on the booking - whether it was for original flight or new flight. When I call back, agent now says that there was a mistake before - the change is actually £220+. At this point, I am in tears, and I've been on hold for 40 minutes

• I call back 5 times and ask not to be put on hold, and to speak with a supervisor. Every time, I am put on hold again!!! This is day 3 
• Finally an agent helps me out by getting KLM Cares to agree to approve my application if I don't fly back. However, the fee now is £83. At this point, I am so frustrated and finally on a tour that I just say go ahead and authorize it 

[4/17 Part 3] Then they call me last night to tell me that my payment is declined. I tried both cards, call my bank 4 times, there is no problem with my cards. The KLM agent actually suggested that I either go to Heathrow (which is a one hour trip and £80 each way) or borrow a total stranger's credit card to pay for it!!! Let me remind you that at this point, it is my 3rd day in London, but I have only seen 1/2 the city and they are asking me to spend 2 hours round trip to go pay.

• Finally another agent investigates and finds out that the problem is NOT with my card, but with the actual ticket. I spent 2 hours on this last night (on top of the 2 hours earlier in the day). So it was not even my fault. She issues me a new ticket and takes the payment. 

[4/- I thought things were finally resolved. When I went to check in this morning, it is asking me to pay another £38 for a second suitcase, even though I asked FOUR TIMES whether my 2nd suitcase was included in the amount. She verified yes - 2 suitcases check in, 1 bag in cabin and emotional pet. - I am on hold with them again this morning. The notes say that the agnet last night gave me an additional suitcase, but that should mean it's the second one, because the original fare I paid included the first suitcase I am beyond frustrated. I finally thought I would see London today - yet, its' noon and I haven't left the hotel because I am still trying to resolve this. I cannot even just say forget it and book a flight with another airline because all of them need 48 hours notice to bring a pet on board. If I had known that it would be this difficult, I would have either (1) kept the original ticket, or (2) just paid for the pet. I need to go to Amsterdam to get my rail pass, otherwise, I would just go straight to Budapest. You guys need to take care of this. Besides refunding me for my entire flight (including the suitcase, that I will probably pay because I just don't have time to deal with it anymore), you should compensate me for all of the time and money I have wasted being here. I have not seen any of London, and I want to extend an extra day to go directly to Budapest, but I need to pick up my rail pass. So I have basically ruined my vacation here because of all of the bad/unclear advice and problems on your side. This is really the worst experience I have ever had. I will be filing a complaint with the Consumer Board in the US when I return home. You need to resolve this right now.
