Vumatel, Worst Service Provider

We haven’t had connection since 16 January. I was on WhatsApp with them for more than 2 hours today. They say they’re working on the fault, but can’t give time of resolution. They’re refusing to send a technician, saying their SLAs are 3 days. I can’t even work at home.Meanwhile, they’re the only service provider in my area, so I can’t switch. This is anti- competition behaviour. Competition Commission? Worst company ever!!
