WATCH STILL NOT WORKING STILL AFTER BEING "REPAIRED"

I bought a watch from Sterns at Greenstone Hill last year July. I took it back in November to have it repaired as when I wore it. It trapped water inside it, on the glass. I collected it on Wednesday and WHEN I got home, the watch was not working at all.

I am tired of this watch, I cannot keep going back and forth to the store and having to wait weeks for it. It is now costing me extra, having to drive back and forth to Greenstone is petrol, e-mailing you right now is data and having to call all the time to find out when its being returned is airtime. I no longer want this watch, it is still under warranty. When I go to the store, may I please get a voucher for my money and I will go and shop at American Swiss for a working watch.
