Very bad experience

I purchased an inverter at Makro Woodmead on 1 May, the amount of R10 999 was approved and went off my bank account but when the cashier wanted to pull the till slip, it was not issued. After spending over an hour trying to sort out the issue, I left the store without the item and out of pocket. I returned to the store the next day and spent another 2 hours trying to sort out the issue. I was told that the money would be refunded to my account. it is now the 3rd of May and no money is in my account. I must mention that Boitumelo was very helpful and issued a R200 voucher for the inconvenience. The issue is still that I have not got the item and I have not received the money back. The other issue is that this is not the first time that they have had issues with the machines at the express till but nothing seems to be done about it. I also live on the west rand and had to drive all the way to Woodmead for nothing. This is very bad service for a customer who always shops at Makro.
