Exchange to be done at the same store

<p>One of the items I bought yesterday I needed to return. So, today I went to the Cavendish branch and the lady did not look impressed at all at the fact that I wanted to return something. Anyways she looked at the slip and said "you want to exchange for something else?", I then said no I want a refund, her response was no they can't refund me. Only after I asked her for a reason, did she give me one. Her reason was that I can only get a refund at the store where I purchased it. That doesn't make sense to me as it doesn't state anything to that effect on your slip, it only mentions the 14day period for exchanges/refunds. I've even had a look on your website and still no mention of this clause. So, how do you expect your customers to know about it when you do not mention it? </p> <p> </p>
