TFG SELLS PHONES THAT DON'T WORK!

I bought a phone on Thursday at Exact. Saturday the phone was locked and didn't want to register a network even with a Sim card in. Sunday the phone stopped working completely. The tfg group really think money grows on trees. Look before I bought the phone the company should have explained to me the policy but in the first place WHY SELL PHONES THAT DON'T WORK. ALL THIS COMPANY WANTS IS YOUR MONEY AND NOTHING ELSE! I'M SICK OF TFG!
