Highly dissapointed

Good day<br> <br> I placed an order for a size 7 and received a size 6 . I tried exchanging the shoes however it does not allow me to . This is not the first time I have had issues . I bought a nixon watch and that was faulty , I bought a pair of nike roshe and that had a flaw in the front part of the shoe .. I never complained about the roshe as I was pushed for time in getting gifts for my engagement . I'm not someone to complain or exchange things however if its my money going to waste then I think it needs to be done . In future maybe your staff should do a quality check on items before sending them to customers .
