Bad service!

I don't even know where to begin, Supersonic is so bad! They kept on locking the router saying I have ran out of data which was not true because when we check on the portal we had data, They double debited me R1198 instead of R599, and when I call them, they kept on putting me on hold, I have spent R500 on airtime just calling them. They couldn't explain why they debited R1198, so I reversed the money and I paid the correct amount. Now they have locked our router and on the portal it says we are owing, I even received an sms and an email from them requesting R1198.

My supersonic account number is S***
