Terrible customer service

Upon returning a pair of inferior quality boots that I had received as a belated birthday gift in February of this year, I was told that because the boots were not in their original condition and because I did not have a receipt, they could not exchange them for another pair or for a different shoe. I wore the shoes once and the inner soles pulled loose and folded up under my feet which is extremely uncomfortable when travelling as far as I do to work and home. Quite frankly, the lady that assisted me was quite rude and had a very bad attitude.
