Firstly I'd like to start with how badly we have been treat by TUI. We booked this holiday last year on the pay monthly scheme that you do, we never missed a payment and was so looking forward to it. Fast forward to more recently on the booking we had hotel stay the night before our flights and parking for the week. We had seats booked or so we thought but I got a message saying time to book your seats. So on Thursday 15th Aug I called tui to discuss this and make sure we had seats. I was informed that our children were free as they are under 12 but I had already paid for them and nothing was said, as she booked our seats it removed our hotel and parking stay. She assured me it would be back on within 72 hours as she had emailed the relevant team, so I called back on Sunday the 18th to make sure as it was looming closer and closer without any word from TUI. Low and behold it wasn't on and left us in the worst situation possible before our holiday even began. We had to pay for a taxi to the airport at 1am at extra costs and then when we got the the airport found out that regardless if we booked seats they get changed anyway. We were seated apart until I told them I refuse to accept that to which the TUI rep was really rude and told us well it's not me that's done it. This caused undue stress to me who is disabled and our autistic daughter. We then went to special assistance at Gatwick and was told it's a 35 minute wait for any help so we decided to try and walk ourselves and this was even before security. We managed to get through there and took our flight out there. The hotel was good we don't have any complaints about that. But the return trip home was horrendous. Firstly the transfer coach that picked us up the driver was the most arrogant Nasty man we have ever met. He firstly told me our autistic daughter couldn't sit next to me as she was a child and told her to go sit further back. After an argument he decided to leave her where she was. Secondly and there is a full coach of people that witnessed this so I don't think this will be the only complaint, there was a car parked in a bay that the driver wanted, he then proceeded to lean on his horn for around 2 to 3 minutes, shouting in Spanish at this lady to the point of her crying with 2 young children in her car. Her husband then came to the coach and they were arguing shouting at each other. To which I said to the driver use the spare bay at the side of them, he then blocked them in in a stand of that lasted around 20 minutes, the TUI rep on the coach didn't look impressed and I told her this sets a great example for your company and she just kept saying sorry sorry, well I'm afraid sorry isn't good enough. TUI has made this holiday hell and our daughter never wants to go on holiday again it has affected her that bad. For being disabled we feel like we have been great disgustingly and I will also be emailing the head of TUI to explain this aswell. I left a review on trust pilot about our experience with the parking but now will updat with the horrendous experience we suffered when we got our transfer. I will also be advising people not to pay for seats as we was told the manifest is looked at the night before and changed
