inferior quality/poor service

Purchased a Fonda tablet fort my daughter on 27th December 2014, this inferior product worked for just over a month then stopped working. We took it into the store where we were told that the a pin for the sim card had broken and it was due to our negligence. This is absolute nonsense as once the sim is inserted into the tablet it wasn't removed. It has now been over four weeks that the store has sent this tablet for repairs and since we have received two calls from the store telling us they don't have a clue as to when it will be fixed. I emailed pick n pay customer care but sadly all we got was a call from a staff member(not a manager) stating the supplier has it and they do not know how much longer it would be. I am really disappointed in the poor communication and terrible quality of this product, had I know I would have purchased my daughters tablet from a reputable outlet. Pick n pay as such a large retail establishment should really try harder to keep their customers happy. My next mail will be to Richard Brasher their CEO, maybe he will take this disappointed customers complaint seriously.
