Debt Settled , still being billed

DMC Gave me settlement figures for 3 accounts which were active by them.<br> I settled all 3 accounts according to their final settlement figures.<br> I received the settlement letters for all 3 accounts from them, yet I am still receiving statements showing I am outstanding on a monthly basis, they have also deducted money from my account which i have not given any permission for and no authorization was signed for it. <br> <br> The accounts have been settled, i want it removed from their system and my name cleared. <br> Its absolutely pathetic. I will take this to Argus Action should I not have final feedback and confirmation that these accounts are closed by the end of the week. I will not pay another cent to them as I have SETTLED THESE ACCOUNTS.
