I'm ****ed off by MTN contract router

I have had the worsed experience with my month to month WiFi service eversince I took it up in April 2023. I always get only 12days of service but I pay the full amount. Worsed of all when I call no one is able to tell me what the hell is going on. But because I can't afford to go somewhere else for now, I'm sucking it up but as soon as financially stable,,,I'm leaving this **** cz wow it's alot...
