Rude and Woefully Unprofessional

We have beeb with Draadloosweb for over a year and a half now. The first few months was fantastic, and to be fair, servoce was great while dealing with call centre agents and their technicians. It all fell apart about a month ago when my husband logged a ticket, querying why our internet goes off at 02h00 in the morning, and only comes back on at 09h00 that same morning, sometimes staing off for 12 hours on some days. The last two tickets logged, they accused us indirectly of unplugging and messing with the CPE (router etc) and threatening us with callout fees if they found out that we messed with it. Further to the fact that it is highly unappreciated that such imolications are made to customers who pay well over R1200 a month for their internet, it goes without saying that compalints should be investigated thoroughly regardless of the internet being back for the time being. Fast forward to earlier this week, the owner had the audacity to tell me that I'm the only one who is complaining and, with that, effectively ending any opportunity to reasonably deal with him. Strangely, after talking to him directly, the internet was fine for 3 days after that. tHis morning we woke up to no internet ONCE again. my husband sent a WhatsApp to the owner's number (as he suggested) and was beyond showcked at the owner's response. the owner feels that we should have invested in the "backup wireless" that they keep trying to use as an excuse for bad customer service and refusal to diagnose a problem. It was said that it's not his issue if we don;t want to pay more, and that the internet was off this time due to cable theft as reported by Vodacom. He refuses to address the fact that badgering a client to get an extra product, just because he doesn't feel like diagnosing a problem is highly unprofessional. I have on numerous occasions requested that they fix the CPE problem that they claim we have, but no one ever shows up. i am currently sitting without internet after it being back on for 3 hours. Everyone around me has internet on the same Fibre line.
