Failure to Refund MY Money!

It's a VERY lengthy story, but cutting it as short as I can: After having made an online purchase where there was some kind of technical glitch, I was told by Hifi Corp that my money could not be found (an amount of just over R1800). After repeatedly asking the accounts department to check, and numerous unreturned calls (even after I had been promised that someone would get back to me) my payment was eventually found. Only at this stage did anyone bother to call me back. After a huge song and dance, and actually taking my husband into a store and demanding to see a manager, did we eventually get hold of someone who promised the money would be returned by the next day. It did not happen. I was then told it would reflect in seven days. This was two weeks ago. STILL NO MONEY IN MY ACCOUNT. This is very poor customer service, and shows a desperate lack of ethics of the company. Not impressed at all. Won't be shopping there again. And I am still expecting my money to be returned.
