Billing department not understanding figures

Telkom mobile has no idea what is going on in their billing department. Twice my account has been suspended eventhough my account is in advance. Spoke to Zamakhosi and she allocated all payments. This morning I get a message my service is suspended. I will obviously get charged another R200 for reconnection. Call and get an automated response saying my account is in arrears. Naturally its on a public holiday so Telkom is a 0 on a contract. So sorry I took out a contract with them.
