contract cell phone

I bought the phone January 2015 on contract,less than four weeks the just went off,I reported the issue to supplier and they promised they will collect the phone for repair. It took them a month + to collect the phone. They reported to me that the problem is software and it will be fixed. They delivered the phone after three months to me.I took the phone when I arrived at home I put my sim card nd da battery. The phone ddnt respond, I put it on charger it ddnt respond.I then phoned them report the issue, they said I must charge it for 16 hours,I did so but the was positive results. I then report again, they collected the phone after a month + for repair. <br> I then get the report from them saying the phone is physically damaged on the battery connector and they not covering the physical damages.<br> They even told me I must take the phone to the nearest repair shop around my area, I did so.the results I got were totally different from I got from jabba (that battery connector was not damaged). <br> Its been a 9 month sitting with this issue
