Worst customer service ever

My ps4 recently packed up and would not work . I took it back to dion wired centurion where it was purchased to have it repaired. After it was booked in it took them 3 weeks to let me know that it was sent to the wrong supplier after this problem was rectified they wanted to charge me R3500 for a repair that is still under warranty I suspect either the dion wired staff dropped it or the couriers dropped it because when I spoke to the customer service manager at dion wired she said<br> That there was physical damage on the machine. But on the job card that they gave me it is clearly indicated that the unit is in good condition I phoned the branch manager his name is marius to find out what was going on but he could not help me as he did not know wat was going on he also said he would phone back but that still hasn't happened I had to go to the store several times to find out about the status of my repair but every time I go there they tell me that they will call on the monday morning still no calls .the job card indicates that if the repairs takes longer than 21 days the unit will be replaced or refunded it has been booked in for 2 months now. This is completely unacceptable
