Inferior quality items and *********** staff

I placed 2 orders online and I don't want 2 orders because of the quality of the items i ordered previously. I want the order be cancelled and my account credited. Order numbers ********** 45035 and ********** 45304. Twice before the orders were not to my satisfaction and I had to go back n forth to the store, not to mention having to stand in long queues. Many items I purchased before were of a poor quality n 5 pairs of shoes purchased opened up and straps cut after. 1 or 2 uses. I didn't bother going to the store to complain as I would have gotten a story about why it xabt be returned. I want theses orders cancelled and my account credited without having to visit the store. The ********** email is useless. Staff are unhelpful. Please sort asap
