Lack of assistance resolving a ********** issue

I had contacted a homechoice agent with regards to a ********** account in my name being used at home choice , which has resulted in my credit record being affected.

Date of contact was 18 November 2019 with reference number being “home choice ***” she promised this should be cleared quickly 30-90 days

I then followed up on 13 February 2020, I got no reply from the agent ( I won’t name the person)

Today it is 27 October 2020 and nothing has been done , I’m now struggling to do things since my credit record is affected, and home choice does not seem to be willing to assist with this issue.

Someone Please do assist !!!
