Constant incorrect online transactions a serious worry!

On 17 March, I tried to book tickets for Cradlestone Mall. After the website failed time and time again and I had to keep logging in, we finally managed to book tickets - only to find out that the tickets were for Baywest instead, and that the money had been taken from my account TWICE. We then had to book and pay the FULL ticket amount at Cradlestone itself, as my ClubCard couldn't be used again. One transaction was refunded by your call centre personnel, and I wrote to you on the 26th to enquire about the second refund, which I had also been promised. I received the following reply: Your feedback and experience allows us to continue to improve and as such our team have closed your interaction as noted below: CAS-143060-C0M1M9 . That means ABSOLUTELY nothing to me, and the money was never refunded. I rep**** to you, and received no response. I accepted that as bad service, but didn't pursue the matter further. Until tonight, when I once again used your webpage, once again paid for movie tickets, the money was once again taken from my credit card, and I then received a message to say 'Oops, something went wrong'. Are you capable of running a webpage, and effecting transactions online? Because it will be a very, very long time before I try booking online again. Except if I go to Nu-Metro instead.
