worst customer service

I accompanied a friend of mine who purchased a tab and within the 7day period the tab gave problems and we took it back but unfortunately they were closed and canal walk was our next best choice... canal walk refused to help us and said we must go back to the store we purchased from and because it was the last day of our 7 days she would send and email to parow to ensure they help us the next day still within the 7fay policy... we did not hear from canal walk again after that and parows manager called us and informed us that canal walk had every right to help us but yet they refused,... the following day we go back to parow Edgar's and all 3 consultants are busy on their cellphones no-one greeted us or offered any assistance... we asked to speak to the manager and one consultant picked up the phone to call her... we waited about 15mins when I decided to call the store and ask for the manager myself while sitting infront of the consultant and immediately I was informed that the manager was out.... I'm highly disgusted with the level of customer service we received and still were told that our story was a lie by a \manager"now we still have this faulty tab and Christmas is in 3 days"""
