Mejuri review: Bold stacker ring

The Store at Yorkdale (the salesperson Julie/Julia), lied to me. I bought the bold stacker ring online. I found out the ring was too small (size 4 to 5) and I wanted to simply replace the ring. I first asked if I could exchange the online, size 4 ring with a size 5 in the store. She said yes. I told her I had a copy of the receipt for the ring. The day before my friend came in to exchange the ring I called Yorkdale again and was told I could do the exchange and there were five, size 5 bold stacker rings in stock. On the day the exchange was attempted, I called the salesperson again (earlier) and was told the ring was in stock (5) and it would be ok to exchange an online ring (received a few days earlier), with a ring in stock and in the store. When my friend arrived to the store that evening, she was told the exchange could not be made. I (the purchaser) immediately contacted Julie/Julia and told her I was willing to buy the ring again. She first said there would be a problem using my credit card over the phone. In the same conversation she said there were no bold stacker rings in stock. This was an absolute lie because I called another Mejuri store in Toronto and asked that they check the inventory for Yorkdale for the bold stacker ring. I was told by the Ossington store that Yorkdale had five bold stacker rings in stock. I don't know why your employee would lie. My friend had to travel via public transportation from Scarborough for two hours to get to the Yorkdale store. I want the ring exchanged. It should have occurred the other day. I want this corrected immediately.
