settled account not closed and homechoice still demanding money

In February 2017 i got a settlement for my homechoice account which was already with the collectors. upon receiving it i paid the full settlement amount to a homechoice account that was provided to me by the collection company. in September i got a call from homechoice collections department calling to collect money for the same account i had settled. when i told them that the account is settled the lady advised me that it was never closed so it accumulated service fees which was the reason for her call. i asked why was the account not closed upon me paying a settlement and she told me that i was suppose to call them and asked for the account to be closed but that was never communicated to me that i was the one who had to ask for the account to be closed. this also came as a surprise to me as i have worked for a settlement department before and once the account is fully settled it gets closed. i refused to pay what was collected and instructed homechoice to close the account but that was never done. i now receive calls everyday from different collection companies for the same account and the amount has escalated. i have also sent numerous emails to homechoice collections department and not even once had i received a response.

i believe this is ******* and i still refuse to pay for an account i settled more than a year ago.
