Account Suspension - poor service

Account was paid 29/09/2015, and was telephonically confirmed with 8ta on 12/10/2015 that they received the funds, however, they still suspended my account on 21/10/2015. WHY??? Have phoned numerous times requesting the reconnection. Every time they say they will phone me back and they never do. Every time they confirm that they see the funds were paid in time (and on time) but still they suspended the account and now we receive threatening sms's from 8ta saying that the account will be handed over. WHY???? Everything is paid. What must one do to get one's account activated again. This is about the 3rd time this year. I have all my receipts for the past 2 years to prove payment of all monthly instalments. 8ta has acknowledged that the fault is on their side, however, my account is still not activated!!! This is very frustrating as I am paying for a service which I am not getting!!!! One reference no is ***8. Still waiting for supervisors to get back to me. Today I was told that I have to wait until Wednesday because today is Friday.....???!!!!!!!!!!
