Terrible attitude at Mall of Africa branch

Monday 2 May I upgraded my contract with Yugen the Manager, although the process took almost 2 hours I was glad it was completed. Monday evening I tried using my VR on the new S7 and it wouldn't connect. Wednesday evening I returned, only to find out the Samsung staff work till 5pm. Firstly this is not communicated at the branch, secondly what is the point of operating till 8pm if the staff we need is not there and the staff you have is not helpful? I had a screen cover put onto the S7 with Yugen who advised i should come back if im not happy. I wasnt able to use the phone effectively so I came back to a very rude unhelpful Dineo on Wednesday evening. She did not make eye contact she didnt advise me on what was going on, she took my phone to the back then returned a few minutes later and then just looks at us. I had to prompt a conversation with her so that she could assist me! Eventually she replaced the phone screen, on my way back to the car I noticed it was damaged, I didnt go back as she was already so helpful and it was late. I spent alot of money with this upgrade as well sa getting this R400 screen guard cover. Please contact me regarding the VR setup, the screen cover thats damaged!!
