Bad service and incompetency

Two days ago I received an email from supersonic for my internet account stating that they haven't received my payment. I called them and the consultant gave me a what's app number to forward to them all my proof of payments. After she confirmed that she has requested my payments to be allocated accordingly then they decided to cut my line at 8pm. At this time their offices are closed. They're the worse service providers with a poor client service. MTN introduced us to this *****s.
