Metrofibre the worse internet service provider

Metrofibre is the worse internet service provider.

I moved to a new place in April, they installed a new router etc, They then sent me an invoice for the router a prorata amount for the month which I paid.

One week later they debited my account for the amount I already paid including an additional amount for the old place which I no longer stay at (bear in mind I did not authorize any debit orders on my account from Metrofibre)

I called them numerous times to resolve the issue, but no one ever answers the phone. Eventually I got hold of someone, they advised that they would inform accounts. One week later still there was no resolution. I sent them numerous emails to resolve the issue, but they still didn't resolve it.

I reversed the amount they debited, today the 21st o May they suddenly suspended my account. I have spent over R300 on phone calls to call them, but they do not answer the phone.

Please can you call me urgently to resolve this because I cannot work, this is a matter of urgency.
