Supersonic terrible customer follow up service.

9 telephone calls to Supersonic since 04/09/2024 to date (16/9/2024) 5 whatsapp messages to their chatline, of which 4 tickets were closed without contacting me back. I called today in final desperation after being told on the 8/9/2024 that a ticket has been logged for a new router as my current router seems to be the problem. I asked for the supervisor and was informed that the person will phone me back. It's now been more than 2 hours since my call. On Sunday the 8th I asked for a technician to be sent out to us as the router only picks up for about 1meter and then you loose internet connection - I was informed that will not be possible, the router is the problem and a new one will be sent to us within 3 to 5 working days, we are well past that date. I am considering at this stage changing my provider.
