Customer service not rendered

I took my wrist watch six months ago to Westgate Branch in Roodepoort West Rand of Johannesburg. I went back couple of times to check on my watch has been repair. Everytime I get there, I am told that it is still not back from repairs. Today the 4th of January 2018 I go back to the branch my wrist watch is not fixed. I am given a lame excuse that it's back it is not fixed correctly. Looking at my nothing has been done. I was not even contacted by the staff that my watch is ready for collection for six months what was happening? Please the manager of the branch to call and explain to me as a customer how is it possible that six months customer has to wait for service. Indeed bad customer service American Swiss not impressed at all.
