Stuff sending me back and forth but yet my refund not paid

on the 23rd of October i bought a jean at G-Star Raw sandton and was made to swipe twice as they claimed money did not show when i swiped the first time but my Bank reported that money went out i then swipe again and they said they seeing the money on their side and bank report that money went out again, and they said the other money would be refunded back to my account the following day, day comes no money i went to store they said they will investigate and call me on Wednesday, Wednesday comes no call and i decide to call them myself and they tell me to come with bank statement i got there a guy i found said there is no need for bank statement money would be paid back to me within 7 days no need to worry and gave me the attitude as if me asking for my 1500 is wrong and fast forward to minutes later when i am on my way home i get a call from the store saying they actually need bank statement to see transaction and i tell them was there and got sent back home , the lady acknowledge that her colleague who said me home made a mistake i then tell them that i am on my way home i can not turn back and give em bank statement as if i owe em money, i then tell the lady to send me blank email so i can reply to it with my bank statement...until now the stored manager never sent me a blank email and when i call she gives me attitude and say she did send it and will resend it...i think their lack of good customer service has made them and whole of TGF loose a good cash paying customer
