Pathetic service

last week Tuesday I bought a phone from your Cresta branch I charged it for 8 hours as told but it started giving issues with the battery dying after 1-2 hours and then when putting the phone in charge it over heats and switches off.

I tried returning it at the trade route branch however they refused to change it and said I need to change it at the Cresta branch, I was only able to go into the Cresta branch today as I stay far from Cresta. however they refused to change the phone and said it's past 7 days so it must go for repairs even after I told them trade route refused to help me.

I also mentioned that I use my phone for business so I can't send it for repairs and they need to change it and they refused.

I'm sitting with the phone currently. it even has false advertising as the box says 4gigs of ram but the phone only shows 2gigs.

I need this matter resolved ASAP, because I need a phone for business and it is risky sitting with a phone that can explode.
