Zales, Grove City, Pa Did not complete a repair or return ring Pa Grove City

I dropped of my ring on 5/12 to have 2 diamonds replaced.  This was a second attempt for one of the diamonds.  They called 5/31 and said the ring was ready.  They inspected it and said everything was fixed.  They did replace one diamond that was missing underneath of the setting.  They never replaced the ring missing on the side. 

I took the ring back on 6/2.  They check it again and said the diamond was replaced.  My husband and I had to point out where the missing diamond was.  They agreed that the diamond was still missing.  They said it was their fault and I would have the ring back by the end of the week. 6/7.  The return date on my receipt is 6/9.  I've been in contact with them and it's a different story everytime. 

Barb told me I would have the ring back by 7/5.  I called 7/5 and they changed the date to 7/9.  I called today and they claim it was shipped out 7/9 and I should have it by the end of the week. 

I have offered to pick up the ring myself, but they won't tell me where it is.  I called their customer service number and she said the ring is in Akron, Ohio.  It has been a unacceptable amount of time.  I want my ring back and I expect to be compensated for the time I have not had my ring.
