Complaint

I'm not happy with the service I received at Totalsports PROMINADE Nelspruit, I bought 2sets of Sports bras which were different sizes as I was in a hurry to fit. I asked at the till if I could return them if they didn't fit. I was told I could. I went back to return and was told that I couldn't. I'm not happy because if I was told that they were not returnable I was not going to buy them. I'm now stuck with items I don't yet I didn't even try on
