Damaged tablet

On 29/02/16 I brought my tablet into the watercrest branch.It had a cracked screen.Which happened while I was flying and was told in store that those tablets are susceptible to pressure changes and this cracked the screen.it was only 2 weeks old.I booked it in for repairs and was told their would be a charge.It went to the repair centre and I got a phone call which I missed but was told it would cost me R860.I needed to confirm that was ok.I had trouble contacting the repair centre so I went to the watercrest branch explained to them that I couldn't get ahold of the repair centre and they took down my job number and said they would contact the repair centre to get it fixed.On 8/03/16 I received a phone call from the repair centre to say that they havnt received confirmation so they are sending back the tablet Unrepaired I explained to them that I spoke to the watercrest branch to say go ahead.But I gave them the ok to fix it while on the phone then.on 22/03/16 I had still not received a call saying it was fixed so I phoned again.to be told the tablet was sent back to the store Unrepaired.when I asked to talk to the manager he was on a call.i was told he would call back. He has not.
