Poor service, time wasted, no result.

I was at the information centre at Woolies Menlyn. Asked the lady, who did not have a name tag on to please check a size of a shirt I had at other stores. She informed me there were no sizes at all stores. However, she said she will check at their stock room. The lady kept me waiting for over 40 minutes. Then I decided to refund the shirt, only to be disappointed once again, the lady at the customer service department instead of refunding the money into my card, she charged me again. Now they owe me double. This is very unsatisfactory. I have to take more of my time to resolve this problem. This was not the first time something like this happened at the Menlyn Woolies. Last year I needed to exchange a pair of shoes, I was sent back to the store I had bought from. I had decided to stay away from this particular store, until recently only to be disappointed yet again. Woolworths Menlyn has not delivered and left me in a worse position.
