Not happy with Fossil service or product

I bought my mom a Fossil watch for Christmas last year. When we bought it, the lady at the branch said that they do not have a stamp for the warranty, but that she will write the details at the back of the book. It states clearly that there is a 2 year warranty on the mechanism and 1 year on the battery. At the beginning of March the watch stopped working. She took the watch to the Fossil shop in Centurion where she got atrocious service and a bad attitude about the fact that there was no stamp in the book. My mom was basically accused of *****. The watch was eventually sent away to have a new battery put in. Now, 3 weeks later the watch has yet again stopped working. Clearly it is not only a battery issue. My mom is an old lady and I refuse to subject her again to the abuse she suffered from the *********** staff at the Centurion Mall. I looked on your website for contact details, but alas, it only directs you to the warranty in a plethora of languages. Please contact me to discuss how this matter will be dealt with.
