Bad bad bad service and a mickey mouse call centre

I have an account with homechoice but unfortunately i lost my job because i couldn't afford to pay so my account was handed over to nimble group by homechoice, i made an arrangement with then and eventually managed to pay uo the account and i received a paid up letter from nimble group. To my surprise i have to send the paid up letter to homechoice myself and im taken from pillar to post by them, they first gave me an email that doesn't work, gave me their legal team numbers which doesn't work or it forever rings without a pick up. I've tried everything i can to clear my name with no luck. I wouldn't advice anyone to pay them once their account is paid up coz they won't clear your name. All they care about is money
