Worst service provider ever

I logged a ticket because our WiFi is down on Monday. It’s Friday and all they do is blame vumatel I’ve been told that they have a 48 hour SLA, then I was told that it’s 48 of their working hours so essentially 6-7 days. No one can give me an eta everyone has an excuse blaming each other and the call center staff are rude and often don’t answer questions or ignore them all together. They quick to lock you into a deal or get customer retention to call if you want to cancel but don’t provide service.
