Supersonic LTE Suspension Of Service

I am so disappointed with Supersonic Fixed LTE by MTN, I have been locked out since mid December until now as they say My account is in arrears. I called the call Centre and a guy checked for me on the system that my 90 day statement reflected that I made a deposit, I was then told the matter will be escalated to Accounts department and they will get back to me after 24-48 hours but I haven’t heard anything from that Department. I was working from home and with no Internet which i paid for but my service where suspended. I’m truly disappointed with suspersonic and I wouldn’t recommend it to anyone. I need someone from Suspersonic to call me and log a collection request of their Router and cancel my agreement with them. Moving to Rain as it doesn’t issues as Supersonic, you just lost a loyal client with your bad after Service.
