Refund Promised

after a long battle with Vodacom The Grove Mall about a tab that they took for repair and promised it will take a week, only to take 4 months, a consultant called on Saturday 23rd to investigate after a posting on hellopeter, and promised to call back, which he did on a Sunday the 24th to say I must go collect the tab, and that as a courtesy from Vodacom, I will get 4 months subscription fee refund as it took me that long without a tablet. On Tuesday that week, my phone was softlocked due to outstanding instalment which I thought since I will get a refund, it will clear it up. When I try to call Vodacom, no department could pickup refund for my subscriptions for 4 months but only R286, which was just on the system but no one could even tell when it will be in my account, I want my 4 months subscription refund as reward, as promised by a consultant on Sunday the 24th April. The call was between 9am and 12 pm, I hope this could be traced and promise be adhered to.
