Passing the Buck

I recently upgraded to the relevant contract that entitled me to receive an R 5000 flight centre voucher. The upgrade was done on 23.12.2017 at the Vodacom store in Groblersdal Mall, Sharon the consultant assisting us (extremely long process) told me that I will receive a link via sms through which I need to follow the steps and by then successfully receive the voucher. By 02.01.2018 I have not yet received anything so i proceeded back to the store and spoke to Mbali the manager, who immediately took offense when my son explained everything and eventually it came out that she never sent out the email. All is fair and she said she will rectify this and then the process will commence as normal. NOPE NOTHING I had to phone the store back and by this time i had become extremely irritated and a gentleman phoned me back and promised that I will receive it by 05.01.2018. and still NOTHING. THIS IS PATHETIC. AFTER SIGNING ANEW CONTRACT AND NOT RECEIVE THE PROMOTION IS UNACCEPTABLE. I REGRET EVER SIGNING WITH VODACOM AND THIS STORE HAS MADE ME SOO NEGATIVE THAT I NEVER WANT TO SEE A VODACOM SIGN ANYWHERE. TOTALLY UNACCEPTABLE. WORST SERVICE EVER.
