Vumatel SADV lousy service

I have been using this fibre service provider for 5 months now. I haven’t had a problem besides the slow network. However my payment was due today, I paid it yesterday afternoon. I woke up to my service being cut, usually when I pay, seconds later I receive a text message saying my service is live. I paid using them same method for the past 3 months but this time it’s giving me problems. The payment went through but I don’t have internet. I’m writing this review because I can’t get a hold of anyone to help me, the number on their website doesn’t work and the WhatsApp number is unattended. I don’t know why call center service is so bad when it comes to ISPs.
