Incorrect billing and bank charges

I have changed banks, I sent my bank confirmation letter to Telkom via Twitter, they said it was sent to Accounts team, at the end of the month they debit from the incorrect bank (causing bank charges of R115). I speak to Telkom again on Twitter and said it's being attended to, nothing happens, the following month wrong account gets debited (another R115 bank charge). I go into store to do this very simple job myself, updated on the system with consultant, thought it's all done. No, it's not done, the next month another debit off the wrong bank details causing a third bank charge (R115) and also resulting an activation fee on my account of R259.<br> I would like this bank charges refunded to me and remove the activation fee of R259 ASAP. And fix the debit issue as well cause I cancelled that bank account. Case number ***1
