Webtickets does not value their customers

My recent experience with Webtickets made it very clear that I am not a valued customer, nor are the company willing to take accountability when their platform glitches. I recently tried to book tickets for an upcoming show. After trying 4 or 5 times to pay for the ticket using my credit card, and their website/payment platform glitching out and giving me an error message, I changed my payment method to EFT. I received an automated email with the banking details and instructions to include the booking reference, and made the payment immediately, understanding that my tickets were secured. Later, I received an email asking me for which seats I had booked. At no time was I instructed to record my seat numbers. When I couldn't recall them, I was instructed to make a new booking in the same price tier - the only problem being that seats in this tier were now sold out. When I pointed this out, I was informed that I needed to pay in for a higher price tier, which was beyond my budget. Essentially, I now have the choice of missing the show entirely and getting a refund, or paying more than I had budgeted for a higher tier ticket, despite the fact that the seats I originally booked were given away through system error on their end, not mine. It took several requests via email to get them to call me to discuss, but they were unwavering in their commitment not to accept responsibility for the payment error, making it very clear that they have zero value in me as a customer. I will definitely avoid using this company wherever possible in the future.
