Telkom

I have a contract with telkom i gave them my banking details from which they must debit, instead they deduct from my old account that i closed even after i provided them with the new account they should debit from. Then i get a phone call from NuDebt because telkom handed me over because they debited from a old account which i closed. Now I try to phone the telkom Tygervalley store where I changed my details and they confirmed that it is changed on the system, I have tried all morning to get hold of someone at the store and the phone just keeps ringing. This is really pathetic to hand over a customer because of their error and poor customer service. They are quick to approve contracts but when there is problem I must struggle to get hold of someone. I have done my part in going to the store to change my details only to find out it still hasn't been changed now I'm getting calls from a debt company telling me i have been handed over for a R139.
