worst service that I have ever signed up for.

ever since the start of this month may 2026, I have been having non stop issues with this service provider ive spent in this week around 600 rands in airtime and data just so I could log into my work, ive called numerous times to the call center and that annoying and ai voice, when I do explain the situation the agent says they will contact me and that they still busy with investigations, its been from Saturday that I have not received a call back nor has the issue has been fixed, note my issue is, I can connect to the internet but sites like my work and some social media sites and banking sites won't work, as if its blocked, I do not use a VPN nor do I put up the firewalls, but when I switch off the wifi service and hot spot myself from my cellphone all sites work so it can not be my devices thats an issue its the line, can I get assistance ASAP and can management contact me acc KUB095
