Bad service from Sterns in mall@carnival

I visited the Sterns in mall@carnival on the 24th March 2019 , 09:57 to book my ring for cleaning and aligning it as it had a crack from an encountered at work. The lady who assisted me that morning was not even friendly and i realized when i arrived home that my slip stated that the job instruction was to replace missing stone. My ring had all the stones attached and i did not bring in my ring for that, i then called the store to fix this on Monday 10:00 and was promised to be called back which did not happen and i ended up going back to the store. They confirmed that the ring will be cleaned and aligned and fix the crack it had. No call was received for my quotation I had to call them back to find out how much the job was.

On the 3rd April 2019 i received a call that my ring was ready for collection, when i arrived my had 1 missing stone and there was even a hole there so you could clearly see the stone is missing. The packaging was already opened and the ladies searched for my ring only to find that another stone came out when they showed me and said they will send it back to be replaced without charge.

My concern is that now I have to pay for a missing stone that i did not know of and it so happens that another stone came out when they eventually found the ring. I will not be paying for the stone that they declare is missing and I have a picture of my ring before it was sent to the store and it is clear that there were no missing stones. The lady who assisted my when I brought in the ring insisted that it had a missing stone and she told me about it she was so rude even the customer she was assisting left the store, this lady did not even have a conversation with me and now she states that she told about my ring having a missing stone.

I would never lie about this and if it was missing a stone I would have noticed because I had the ring in my hand for 2 years now.
