Fast Fix Jewelry and Watch Repairs

I gave these guys my watch to make some adjustments to the speed cause it was very slow. They did make it faster, but when I got it back, water started to get inside. When I took it back based on their warranty, they said my watch wasn't water resistant which it was. I insisted that they fix their work. They finally accepted and made the repair. When I came back they tried to charge me $150 to get my watch back. I made a scene and they gave my watch back. The watch is fine now so their initial workmanship was not very good. The owner told me to never come back and I assured him I would not. I wouldn't trust these guys so watch out.
