Where is my watch??

Beginning of this year my Guest watch stopped working. I took it to Diamond & Pearls Jewellery store in the mall @ Carnival. I requested a new battery and was told that it would be R50 for a new battey. I was told that it will be ready in a couple of hours. I returned back after a couple of hours and asked if by watch is ready. They said that it was not the battery and that they would need to send it in for repairs. I agreed to send it for repairs. They said in would take about 6-8 weeks for the watch to be repaired and that they will send me a quote before any repairs are done. I never received any quote. I had to keep phoning to find out about my watch. Evenually, I was told that it would cost R453 to fix. I gave the go ahead and now I am still waiting for my watch. It has been 9 months now and still no word on my watch. Where is my watch??? If they have lost my watch, just say and either replace it. It is getting to the point that I am thinking of going to the police and putting in a charge of theft.
