Terrible customer service and refund process

We purchased tickets to Krone 7 back in 2021. The even has been cancelled twice now and we have been offered to either keep the tickets or receive a refund, I opted for the refund.

Needless to say its been over a month, 23 working days to date and I have yet to receive my refund. I have send numerous emails without a response. I tried my luck on Facebook Messenger and my message was read without a reply. I have phoned a number a times and they just keep saying it is in the process. At this stage I am beyond fed up. Stop telling me it is in the process I want a clear update of when to expect my refund.
