******* with poor follow up customer service

I booked 4 tickets to an event and paid. I received a confirmation email that the tickets had been reserved and that the payment would reflect on my bank statement in a few days. Two days later I received not one, not 2, but three bank notifications of the money being deducted. I contacted my bank to confirm and they did confirm that the amount had been deducted three times instead of once. I contacted computicket, and they could not even find my booking on their system and advised that it may have been deleted. They requested confirmation of the deductions from my bank as well as the email from them confirming the reservation of the tickets, both of which I sent and they confirmed had been received. It was taken to their finance department who would not give an answer and advised that they had to wait to see if the money actually reflects in their bank account ( in the meantime I am out of pocket over R1 800 with no tickets) . The agent that I was dealing with was initially very helpful and promised to follow up with me, however despite multiple emails, I have yet to receive feedback regarding this problem and the way forward.
