loss of goods

I brought in a Tissot watch to be fixed in April. They lost the arm of the watch. They promised to order and replace the arm in May 2015 and I have been waiting ever since. I called in again on the 3rd of August and I was promised that the missing arm of the watch would be in for me to fetch the next week. But This did not happen. <br> The staff and manager seem not to care about this problem. I would not refer World Time Machine to anyone. Their service is just ridiculous , and they seem not to care about the client. I regret having taken such an expensive to be fixed there, only to have them lose its components then procrastinate at having them replaced.
