Over-charged and disconnected in error

I upgraded my 2 contracts with Telkom Mobile on the 23rd October 2015 ( R1499 unlimited and a package for R499). Nothing should have changed. Last week i was presented with a bill of +R5034 and politely disconnected because i didn't pay the amount in full. On Thursday last week, i went into Telkom Cresta, was told that i should pay an amount of R1603,42 in order to be reconnected. The consultant we spoke to confirmed that the billing was incorrect and while standing there, he emailed the customer service quering the amounts. We then went into ABSA to do a direct deposit into their bank account, went back to Cresta with proof of payment, which was scanned and sent through to customer services for reconnection. We were told that the reconnection would happen on Thursday. Friday morning, still nothing, so we called the 180 and the person we spoke to said that we were given incorrect information but that it would be done on Friday. Saturday, same thing. Well as at today, we are still not connected. I have spoken to probably 15 people in the call centre, all of whom have different versions of reconnection lead time. And its been escalated 5 times by team leaders. What shocking service!!
