Telkom disconnecting paid account??

This is the 2nd month that Telkom suspended my account, due to an error on their side. Month one, the debit order was run for an incorrect amount. Now, my debit order went off on the 24th of January and I kept receiving messages to pay my account. Last week I contacted customer care and advised them the account was paid (by debit order, which they run) and asked them if I am going to have a problem again where my account is disconnected. I was advised that I would not. Surprise, my account has been disconnected. I logged 2 requests for Telkom to contact me (as I can not phone out), just for them to phone and drop the call on me.
