Account information not fixed

Still waiting for my bank details to change. Two months ago I changed my bank details for my debit orders and when I checked my old account statement I picked up that the telkom debit order tried to be deducted from that account! The whole point of changing my account is because I moved my salary over so there are no funds in the old account. I've had to call four times to change my bank account on my telkom account, now I have bank charges that are due on the account of R400 and Telkom wants to charge me an extra R200 to my bill due to the transaction declining! I wasn't this sorted and I want that amount free for the inconvenience and also to cover my bank charges! Someone better get back to me asap!
