Locked Account, Supervisor Negligence

I requested on 29 July that my phone number had to be changed on my account at your Somerset West branch. The supervisor (a guy, don't know his name) assisted me and I filled in a form that he allegedly sent to complete my request.

I have however not been able to use your services via the number I've requested the change for as it says my Id number has not been found.

Yesterday (13 August) I went back to the same store to find out how much credit I have, just to find out that I have no credit, and was informed by the same supervisor my account has been blocked due to my request of changing my phone number was not done correctly in the first place, he was supposed to send a copy of my ID to your offices and did not do that, and blamed the call center for not informing him on this matter.

He told me all would be fixed by yesterday and I would receive confirmation via sms. This however is not the case and my account is still blocked(checked on your website).

This is UNACCEPTABLE and needs to be rectified as soon as possible, as I'm unable to make any purchases and will miss out on your promotions.
