Accounts Not responding

After receiving a feedback from accounts department saying that someone will contact and sort this.problem out, we are still sitting with the same problem, and for the past 4 weeks, we did not heard anything from Telkom!!Received an sms that account will be deducted again with R1500 which we will go and reverse again, due to people not communicating!! We will do this until someone from Telkom accounts department gets in contact with us, to sort this out.... the agreement was to pay monthly and now they want to take the full amount of our account, which WAS NOT AGREED to!!!
