Bad customer service @ furious customer

Woolworths Wonderboom Junction is full of nonsense. On the 27th of June I went there to do my grocery shopping and my card was debited twice (double payment) after receiving two notification for the same transaction I immediately went back to the shop and they told me it happens a lot & I should worry the money would be reversed within few hours and if I don’t received my refund I must go to the shop after a day or two with a bank statement and I accepted that nonsense. Few hours past & nothing happened, after 3 days I decided to go back to the shop & this time I was told that I need to wait for 7 working days meaning I need to go back to the shop on the 8th June & this time they said they’re not promising anything since they still need to investigate after this so called 7 days. I really don’t know why I must go back and forth for my hard earned cash, Woolworths I want my refund period, the double payment is even reflecting on my back statement, not sure if you’re shop at Wonderboom Junction is ****ming it’s customers. I called your customer care on the 1st of June and I spoke to Ayanda and the only thing she said was “I’ll forward an email to the store manager in Wonderboom Junction he/she will call you in few hours, today is the 4th of June & I’m still waiting for the phone call from the store manager. I’m really disgusted and dissapointed at how Woolworths is failing to resolve such a small issue, my time, petrol and airtime get wasted on my side as I try to get my refund back.
