Very unhappy customer

I took my Skagen watch in for a battery replacement at American Swiss Langeberg Mall in Mossel Bay at the end of May. My watch was damaged when they tried to open it to replace the battery, and told me that my watch is not working. They were unable to close it again and asked me to take it to another jeweler in the mall to close and seal it. He pointed out to me that my watch has been damaged. When I took my watch back to American Swiss the advised that they will send it in for repairs. It will take 6-8 weeks and I will receive a quote which I will need to approve for them to continue fixing my watch. I was unhappy that I would need to pay for their mistake. I never received a quote. Upon phoning American Swiss they advised that my watch has returned and I need to pay R750 to get it back. I told the shop assistant that I am unhappy with the amount that I need to pay and that I never received a quote to approve. She advised if I don't pay they will need to return my watch to the repairers. I was always an American Swiss supporter but I am extremely unhappy with my recent experience and doubt that I will ever support them again.
