poor service

I bought a dress at Workshop branch for my daughter on Friday. It was too small so I returned it. On returning it it had make up marks which were there when I bought and I think was the reason why it was on sale. I returned it Saturday morning to Pavillion and was told they cant except it because they did not write on the receipt that it had make up. So I had to come back again when the manager was there. I came back again today and was told manager is not there again. So now il have to make another trip for a R90 dress. At whos expense. If that manager dies will I now not get my exchange?
