unsatisfactory service

I bought a tablet at Donna Claire before the 7th day the LCD got damaged went back to the store on Sundays 2015?329 and ask them to send the phone to the technician who will determine whether the damage is the manufacturers fault or mine since they couldn't assist in store insisting that we've damage the tablet <br> On Friday 2015/04/10 I received a call from Donna Claire sales assistant informing that its going to be costly sending the phone back to the technicians I told her money is not a problem but she started having an attitude on the phone I told her I was actually waiting for a call from the technicians not from the store because none of them are technicians she carried on <br> I would like to be assisted because now I have to pay for a phone which is not working since I bought it on my Foschini account <br> I tried to call their customer service at head office and I hold forever without being assisted ,I want a replacement on the Tablet or for my account to be credited because it took 2 full weeks for the tablet to be send to the technicians and now my son who is in matric is struggling with his work.
