Metrofibre need to get their house in order

I have two major issues with Metrofibre. Every month it takes them very long to allocate payment to my account no: DEB472. I have paid the full amount of R599 over a week ago. Although their Account Department confirmed receipt of the funds, it still has not been allocated and they have suspended my Internet Fibre Service. This is very bad service. Then Metrofibre has for some reason, unknown to me created a second account number for me, against my ID number (DEB487). Even after informing them numerous times on email, SMS and WhatsApp, they are still harassing me and handed me over to collection Lawyers for the amount of R646,14. now the lawyers have also started phoning me. This is Crimen Injuria and harassment. This is effecting my credit score negatively. They need to get their house in order and rectify and resolve my issues.
