Damaged goods,Bad customer service

I bought a watch on the 20th of February 2018 at Clicks Mokopane on the 23rd of February 2018 when I took off the watch,the strap came out/broke,I went to clicks Mokopane on the 24 February 2018 I asked for the Manager,Violet to help me,I arrived there at 13:00 ,i tol the manager i was there to return a watch,the manager did not even apologize for this incident,she just told me there's no guarantee for the straps only for the battery,When I asked her to call head office for me,she just handed me a slip from the till with head affice's numbers and I asked if she could call them for me but she told me they are closed which I found unusual because they were closing at 15:00 ,I asked her how can your head office close at 13:00 whereas you are closing at 15:00 she just looked at me and did not answer,that was so rude,I have never experienced such pathetic service from a manager,I expected that from junior staff,on Monday 26 February 2018 I phoned clicks head office and told her about my complaint,she said she was gonna get back to me,till today I'm still waiting and its Wednesday.I bought this watch for R180 nogal so my R180 just went down the drain,from all the years I have being a loyal clicks customer I never expected to be treated like this.
