Second Sony Xperia Z3 in two months

After a week of handing in my Sony Xperia Z3 for repairs, it will not charge at all, it now has to be handed over to an advanced technician to solve the problem. When asking when it will be handed over, I was told it would probably happen on Monday only. Why wasn't the phone given to an advanced technician from the start? Why are you wasting my time and money? Will I get discount on my account because I could not use the phone on your network? Will I be refunded for all the applications that was downloaded on the phone using my data I paid for? Cell C, can you please prepare yourself for the transfer of all my contracts? VODACOM SUCKS!!!!!
