Repairs

I had brought in my Iphone 6 for repairs on the 26 of Jan 2016,I received no feedback from anyone to tell me that my phone was fixed.I had to take initiative to follow up if my phone was repaired.I was then given my phone back,only to find out that the back cover was not inserted correctly,which was then escalated to the manager of the store and assured me he will follow up with me the next day.Guess what?nobody called to follow up then i had to take time out my day on Thursday to check up on a phone that is the stores responsibility to update me.I was then told that they do not know where the phone is and will call me on the Friday.Guess what?No one ****ing called me,I am sick and tired of taking time out of my day to follow up on a phone that is the stores responsibility.There are never managers in store,staff members are always confused and cant divert the right answers to me,the in store phones are never answered by anyone.What is left is to ****ing cancel this stupid insurance with vodacom because its clearly useless.The service Im receiving is unacceptable and I have had it with this store.They move and dont tell clients that they have relocated.
