Staggering lack of workmanship and integrity

I took an antique aquamarine beaded necklace for restringing to Pearl and Diamond Design in Clearwater Mall. When i got it back, beads were missing, making the necklace uncomfortably short. With many apologies, the staff took the necklace back, but when fixed, there were even more beads missing, making it so short it was impossible to wear. After more back and forths, the manager intervened, and with profuse apologies, assured me that he would source beads to match the original ones, and ensure the necklace was returned to me in its original condition.

Upon completion, the necklace was restrung it to its original length, with quality I would expect from a five year old. The missing beads were not replaced, resulting in huge gaps. I called the manager, who told me this was his last week working there, but he had conveyed the situation to the owner, and there was nothing he (the manager) could do. He recommended I complete a complaint form, which goes directly to the owner, who apparently takes complaints very seriously. I sent the complaint form two weeks ago.

The state of affairs, after nine months of back and forth, is that what was a beautiful antique necklace been destroyed. The restringing is embarrassingly shoddy and amateurish, a good number of aquamarine beads have gone missing, and it cannot be worn in the state i received it. What shocks me the most is that the owner clearly accepts both the staggering lack of workmanship and integrity of his staff.
