Homechoice - Beware don't do business with them because they don't want to let you go once you start.

Hi had a homechoice account and paid it up in December 2020. I then instructed homechoice to close my account and send me a letter confirming that it was closed and paid up. I then received an email stating that thr account was paid up and I took this as confirmation that it has been closed. 8 months later I received a statement from them and was shocked because I was under the impression that the account was closed. I then called and requested fornitnto be closed and was advised that it cannot be closed because there is a credit and they need to refund me. I told them to write the credit off and close this account ASAP as I no longer want to deal with them. It has now been exactly 1 year 5 months since I requested for this account to be closed and still nothing. I sent of 15 emails, made over a dozen phones calls, I even chatted with a few agents on Facebook and all promised me that my account was closed and that I will receive my letter in 14 days. Well it has been 18 months and still nothing. I don't know what to do anymore and everything i done is in vain because nothing comes of it. This account is now affecting my credit profile because it is reflecting as a open account.
