Bad attitude and unfair play

The watch stopped working so I took it to another Cajees franchise. They told me it was not the battery that was flat but rather that the watch needed a service. They then told me that the watch has a two year warranty. So I should take back to the store it was purchased from with the warranty slip. I then asked what the warranty slip was and they told me that with every guess watch that is sold they give a slip with the date of purchase and this counts as proof that the watch is under warranty and that it was purchased from them. I went to the store without the slip and asked them to fix it. I explained that the watch was a present and that I was not given a slip for the warranty. The lady in the fourways mall branch was extremely rude had a bad attitude and spoke to me like dirt. She told me that she could not prove that the watch was purchased from them as the store is now under new management. I then asked to see the book where items that are purchased are written. Eventually she showed me the books after she said she didn't have any books I showed her the proof in the book and they refused to service it. Even after proof. I will not pay for it to be serviced
