Terrible Customer Service - American Swiss BlueRoute

My fiance and I took my engagement ring to get sized last week Thursday. We went by Wednesday evening to enquire about the process, we were advised to bring the ring and slip before 10am Thursday morning&I could receive my ring on Monday. My fiance went first thing Thursday morning to drop off my ring. On Monday he went to pick it up and was told the ring was never picked up. Neither of us had been contacted to advise us of this and the assistant in store also went on to make accusations stating it was his fault my ring wasn't picked up and we came late Thursday, he then stated we came Wednesday and her reply was simply "Oh" she didn't even have the decency to apologize for her accusations. I went on to send an email complaining about this horrible experience Monday evening and still no one has gotten back to me.
