Poor customer service

On the 3/03/2019 I made a payment at Game Jabulani. Which on the 7/03/2019 I got a notification saying I have paid. On the 10th I went to the store to enquire but paying. Which they said they are slow to process the bebit card payments. They requested proof of payment which I proved a bank statement, till slip and I was advised that this will be resolve with in 7 working days. Now the problem is its still not yet allocated. The collections team calls me everyday sometimes twice a day to make arrangements they so rude to me. I have been to game store about 10 times now since the 10th. When we call thier guys to allocate payment, we spend over 30mins on the call then they advise that have everything they the money will be located with seven working days, then after those I do a follow up they sayv they didn't receive documents (proof of payment) which I forward again and they confirm that they have it. Sadly the next week it's same story. So what am I suppose to do now as sick and tired going to game store jabulani am ?
