Pathetic service from Game

On 1 Des 2017 I opened a new Vodacom top-up account at Game stores Potchefstroom. En January I received a bill for an open account. The issue was raised with Martha from Vodacom at Game and Sipho th store manager. Another account for again more than R2000 was billed against my name for end Feb. They confessed that the accidentally oppened an open account and not a top-up account, but couldn’t come with an answer on how this will be recified. They promised to follow up, but to date no answer. Contacted Amid from Game head office who also came with empty promises. The last promise was that my money will be refunded by Saturday 3 March. Didn’t receive a payment and also no answer. Phone numerous times, but the store and head office is avoiding me and only making empty promises when I eventually reach them. Would please like some urgent answer on this as it seems that Game is not at all interested in refunding money they stole from customers.
