Happy to take your money, won't actually provide a service

I first logged a fault with my fibre on 9 February 2024. Today, 5 weeks later, my fault has yet to be resolved. I get escalation mails until they run out, then dead silence. I contact support again, then I am requested to go through all the same troubleshooting steps again. I have had to do this 4 times already. Absolutely nothing has changed, and they refuse to send a new router or a technician.

In addition, at the end of February, I contacted them to request a credit as I had not had service for 3 weeks at that point. They issued the credit AFTER they charged me for the next month. They refuse to give me my money back (their support person said they were checking and then waited for the timer to run out and the chat to close automatically). They have now charged me for a full month and provided no service.
