Bad customer service

I have connectivity issues with my home fibre, called vodacom on the 7th of Jan 2025, was given a reference number and promised that a technician will contact me. Till this day, I am still struggling with connection, nobody has called me from vodacom to resolve the issue, every time I call in, they simply reboot my router from their side and it works for 2 days, tops. Then I have to call again. As a paying customer that never misses my payments, and a person that works from home, this is really frustrating and putting my work on the line due to your incompetency. I was utterly shocked when I called yesterday (27/01/2025) to follow up, and I discovered that my ticket has been closed because "issue has been resolved"....TOTALLY DISGUSTING!!!!!!!!!! Vodacom can surely do better
