Debit order not changed

I went to Eastgate Telkom branch to change my banking details to my new account. I waited for about 45 mins int he queue to get attention. Thereafter, the consultant confirmed that she had updated my debit order banking details to the new account. I asked for a confirmation and she assurred me that all is fine. Come month end the debit order goes off on the old account. Isnt that pathetic? What kind of service is that?<br> <br> I cant imagine joining that queue again to do the same process.<br> <br> Stuck with Telkom because i need them for a telephone landline.
