Absolutely terrible service

My fibre line got damaged on Monday the 14th. Called supersonic as my ISP whoopened a case with Vuma. ISP 488665. Then on the Tuesday morning vuma phoned me. They were at the completely wrong address supp**** to them by Supersonic. I called supersonic again. Spoke to an incredibly unhelpful technician. (Who could see the incorrect address on the ticket, despite having the correct address as my billing address) The line then cut and she didn’t bother to phone me back. On Thursday I had still heard nothing. We phoned 3 times to finally get help, only to discover that our address had still not been corrected with vumatel. They then opened another ticket (ISP-491322). Today the 18th I called and insisted I speak to a manager. Francis was the one I spoke to, he contacted vumatel and said I should get a call in the next three hours. He said he would follow up at 14:00 with me. It is now 15:00, I have been on hold for 30 minutes trying to get hold of him as he never phoned. Still no feedback from anyone. My wife works from home, this is costing us money. Supersonic couldn’t care less and I can’t deal directly with vumatel. Ridiculous. This should have been resolved on Tuesday already (had supersonic submitted the correct address)
