Poor customer service from Computicket

I purchased a ticket online on 2021/10/13 at about 05:13 on computicket travel for 2.2k and their system said transaction was unsuccessful and the funds have been deducted from my account, I waited for a confirmation for my purchase and it never came, I then contacted them and I was given the run around, I finally spoke to one of their consultants who seemed willing to assist and she requested me to email proof of payment and I did, I was then told that my refund would be processed within 3-5 working days, after a day was contacted by the lady who helped me and she informed me that my payment is not reflecting on their side and I should contact my bank to reverse the payment, I contacted my bank and requested them to reverse the payment, I received correspondence from the bank that the computickets bank has refused to reverse the funds back into my account for reasons that where apparently private and confidential, I then reverted back to computicket and no one is willing to help me to date. Query logged on 13 October 2021 still unresolved.
