bad customer satisfaction

I bought all star sneakers on the 20/12. Its been a week that I've been visiting the store to get a bigger size. The sales people were friendly and eager to assist in finding a pair for me. They kept on telling me they would receive stock the next day. When I got to the store there would be nothing. I wanted to refund them and was told I can only get a giftcard which according to them is store policy. I spoke to the BM about the refund and she also told me about the policy. I furthermore asked if the policy was meant for specific customers because my husband returned stuff and was fully refunded and I left. I called their H/office who in turn forwarded my call to some guy called Jacob who also told me about the policy. I asked him why is it that when we purchase we are not told of their refund policy but have that written only on tillslips? Are they only happy to receive money and don't want money out of their store? Not that there wasn't any in the store or that I'm desperate for cash. The response I got from the BM and the Jacob guy shows that their staff isn't properly trained in customer care. They have a DONT CARE ATTITUDE which is not good for business. Ill take this further
