Unhelpful and unprofessional experience

I purchased a men's ring online at sterns a few months back, received the ring and it was too big, so we took it to sterns in blueroute on the 9th of March to be resized. They have on their system that it was sent to the jeweler on 11 March, we got an sms to accept the quote for the resizing and we did even thought the cost to resize was more than the actual ring costed, we accepted the quote because we were getting married on 30 March and needed it done, we were assured it would be be back in the same week (11- 15 March). By the 21st we hadn't yet heard back so we went into the store they sent an email to the jeweler and assured us it would be there by the 25th. By the 29th we had still not heard anything, went back into the branch and were informed that they STILL didn't have the ring back and offered no solutions for the fact that we needed a ring for the next day and had the audacity to suggest we buy another ring from them. I ended up going to a different jewelry store and needed to purchase a ring because I refused to spend another cent at sterns!
