personally did it in the branch

I canceled my telkom account in the beginning of december as i was moving to Australia.. I went to the branch to cancel it personally and left there having been told it is cancelled.. As it was beginning of december i still had to pay end of december for said month which was fine..A few months after moving to Australia i noticed im still being billed R700 each month as my debit order was set to that being my account was only R630 each month.. After noticing I'm still being billed i went on to the telkom website to look at my account..after 5 months it was suspended for being R1500 in arrears yet my account was debitted the R700 each month which in itself should be impossible.I'm sitting overseas now unable to call on any of their numbers to find out whats happening as the machine tells me my account us suspended and then i get disconnected.. I'm not going to pay AGAIN for an account that was closed 5 months ago..i want my account closed and my money refunded because this is *****..
