Newport Branch Tui Absolutely appauling customer service. Mis sold holiday by £1500. Told one price by the representative that sold it to us, to which they added extra notes detailing the breakdown of each cost for the holiday to our booking documents. During the original booking we paid to pre book seats due to our party consisting of four different families, making up 14 of us travelling in total. Including one diagnosed autistic, one going through autistic diagnosis and an infant with a rare genetic conditioner, going on the first holiday of their life after numerous surgeries.   Postponed the holiday in 2021 due to health concerns and restrictions that may be in place that a diagnosed autistic child may not be able to understand. To be told by representatives at the Newport Branch that we would not be able to postpone our holiday we would have to re book as a new booking, but have to pay amendment fees o the new booking and would lose our pre paid seats because of it being a new booking! When the representative was questioned about these issues they consulted with another member at the Newport Branch which resulted in our amendment fees being waivered down to welfare if we could provide proof, which we did, but could not help us with anything else. At this point the money differences still wasn't picked up as the representative used the notes placed on our booking documentation to work out how much extra we would be paying per family to postpone our holiday! When looking at paying the holiday at the beginning of 2022 we found the discrepancy (£1500) between the price we were sold, notes to prove from the representative, and the actual price of the holiday. Newport branch Tui's response was there is nothing they can do other than re book, even though it was not our fault. When trying to explain our issue the staff member’s dealing with our query were reluctant to listen and defence. They asked us to prove that the representative had mis sold us the price, which we did by telling them to go onto their own system and look at the notes on our booking. They then left us sat there for 20 minutes while they discussed us on the opposite side  the room even though they had all the information they needed on the computer in front of them and us! For them to come back and tell us it was OUR fault and we should have picked the discrepancy up!! We were told we would have to pay the extra or rebook, but if we rebook we will HAVE to pay the amendment fees or it won't be possible, it's not the branch's fault. When I questioned why we would have to pay them when had we been alerted to the discrepancy when we rebooked in 2021 we would never have stayed with our original holiday and we would not have paid the amendment fees like we didn't then. Apparently because it was a new booking, like in 2021, we would have to pay amendment fees. It was pay that or we would be unable to re book. Told by the Newport branch to complain to head office to TRY and get our money back. Exhausted at the lack of customer service, apart from them easily finding more hurdles for us to jump over we decided to pay. The situation then got worse!! We were told they would price match the holiday we found, but was unable to, then came more of the excuses why they couldn't price match!! 'It is for new customers only' even though we were being classed as a new booking. 'Its online offers they can't get instore' even though the representative had to go online, same as us to book our holiday because they were unable to use their own system for such a large booking. I have sooooooooo many more issues and apparently nobody in the Tui group wants to know. One word for some f the members of the Newport Tui Branch INCOMPETENT.  I've been told by the Newport Branch they can't help, to be told by Tui messenger that they cant help it should be the Branch who sold it to us and Tui live chat that's ends your calls even when you agree to wait in the queue. We are fed up if jumping hurdles to rectify a problem caused by Tui, to be met with more problems caused by Tui and then no one in Tui wants to give us solutions to the problems they've caused!!
