Failing to repair my phone

I bought a phone and after 1 month and 3 days it didn't charge. I took it back to Game and told the what the problem was and they took it to repairs. It came back from repairs with the very same problem of not charging. When I took it back they said I must take it to their repair center of which I refused. Now I wan my money back as they are failing to give me proper service and I am spending too much money travelling to return a cheap phone that my petrol costs will end up being more than the phone itself.
