Time for a change

I phoned the service center on the 29th of June to change my bank details. The lady told me that I will have to pay and extra R 100 to change this with the bank. I agreed to it and she told me that all was changed and they corrected the banking details. On the 1st the debit order went off my old account. It was returned as the account had no funds because I don't use that account anymore. It was then obvious that the banking details were NOT changed. On the 2nd I did a manual EFT to pay the outstanding amount. I noticed on Sunday that my data had not been updated on one of my 3G - so I phoned Vodacom again. I was told that my account is in arrears and the money will be taken of my account on the 7th. WHAT????!!!! So now Vodacom just decides to take money off my old AND my new account??? And then they still expect me to pay the extra R100 - \because my debit order was rejected". That is NOT what I was told that R100 was for. My debit order wasn't rejected when I phoned on the 29th. That R100 was to make the change. Does ANYONE know how to do their work at Vodacom???!!! I've had my hands full with Vodacom this year already. Time for a change!!! Definitely!!"""
