Samsung Tygervalley

On December 08/2017 booked in my Samsung Galaxy S7 Edge) for repairs (Small crack on screen) (REF # ********** 428) at the Tygervalley Samsung Store. I was told my repair would take 2-3 weeks. I went to the store on the 29/12/17 and they could not give me any updates on my cell phone. The service advisor in the store said they are still waiting on parts. I then went back on 05/01/2018 and still no proper explanation was given on why it is taking this long to repair my phone. Until now I still don’t have a cell phone. I was on leave in December and is back at work, so I need the phone. The lady in the store said that she doesn’t get any feedback from Head Office.I called their Manager Chad and he said he would get back to me but until now I am still waiting, there has been no explanation, apology of any kind
