Disappointed in Zama Cele Telkom customer service agent

I am very upset with the way Zama Cele handled my call. I have contacted customer service to change my bank account number and also asked for advice on how to make a payment in order to avoid the line being cut since im working from home and the account number will only be updated from the 1st of next month. She tells me that if I don't have the money 10 days before debit order date then she don't have know. I mean what kind of advice is that even. Why did I then contact customer service to get such an answer. I'm pretty sure there are other ways to go about paying the account. I have never had such bad experience with Telkom ever before. She needs to change her attitude as she works with customers all day everyday. That is not the way to handle a query. Regards Madineah ***
