Cell c bad service Uitenhage

Im very disipointed in Cell c in Uitenhage.I have a laptop contract that n pay R530 every month on time.In my opinion if you get a new oroduct from them they must open it in store to make sure it is in a very good condition and working.But the day ive revieved my laptop cell c didnt open the HP box in store infront of me.Ive opened it at home and ive seen a little crack ontop outside on the right side.I went insore to complain but the lady in store said to me i mist contact HP customer care.So i did after many atemts of sending them emails ive never recieved any word back from HP.But ive left it there because it was working 100%.So a few months back the optical drive started making a noise and at times didnt eant to open at all.Ive went to cell c again and the said i must contact HP myself.So after sending a few emails to HP again ive recieved no answer again.About 3-4months agou my laptoo didnt want to turn om when i switched it on.So the same story cell c said that i must contact HP.Sal after allot of emails ive finaly got thru to someone that can help me.But now the platinum Warranty company want proof of tge fact that ive reported the crack to cell c here in Uitenhage.And said this was almost a year and a half ago.So how can i resove this matter?The laptop is stil under garentee and im paying cell c every monyh on time.They dont wait for their money at all.
