A real Ripoff

I bought a Mint Fox cellphone on the 22nd of August at Dunns in Promenade. The phone was not checked and when we inserted the sim would not read. I took it back to the store a week later and I was told that the simcard mechanism is broken and that the phone has to be sent away for repairs. The phone came back a week later still broken. Now I am sitting with a brand new phone that I cant use. I need someone to contact me regarding this poor service. And please DO NOT phone me to imply that I broke the phone.
