I'm not a ****!!

My husband and I bought 3 pairs of shoes a week ago. Today I brought back 2 of the 3 pairs because they hurt my husband really badly! Not only did I not expect green cross shoes to hurt so badly, but was then told by the staff that we must wait till tomorrow when the manager is back 'because the shoes had been worn and they cant resell it'. WHAT?? You cant refund me unless you can resell my worn faulty shoes?? And you cant refund me because you blame me for a manufacturing issue? Rediculous!!!!!! I will never buy from you again lest I buy someone else's returned shoes!! Customer experience a total fail!!!
