Vodacom warrenty does not apply

I took out a contract with vodacom February 2014,blackberry 9720.The battery connection had been faulty & the phone kept switching off randomly,I took the phone back to the vodacom i got the phone from & I was directed to go to a vodacom care,where I was asked to book the phone in for assessment.I wasn't able to book the phone in due to not having another phone to use,so i stuck it out & I just used the phone.Co-incidentally end of January/beginning of February 2015(1 year)the phone was not charging properly & then stopped charging at all,I was charging my battery for a week in a colleagues phone to keep my phone alive.I did forced the phone to charge in frustration but only after it refused to charge after countless attempts.Finally i had no other choice but to book my phone in to be sorted out,Especially since its only been 1 year & I have 1 year of the contract still to go,Cant buy another phone now or take out a new contract.I booked the phone in & the consultant noted everything,the phone appearance and condition was good,&amp
