Misselling

In 2007 I was sold a Kirby Vacuum by Easy Care Promotion and realised before the order was delivered that I would be on maternity leave by the time my first payment was due as my baby was due in November 2007 .I advised Easy Care Promotions that this was the case and they advised that because it was Friday in August that they delivered their offices was closed and they would leave the vacuum at then my mom's house and collect on Monday, they never collected and I called them numerous times and they just insisted that they would collect, I delivered early in September 2007 and was hospitalized for a month , and had alot of complications with my baby who is now 13, In 2008 I lost my job and decided to take care of my premature baby, I kept getting calls from CTI Financiers and the more I explained what's happened the more they insisted that I should pay which I could not add 50k was a huge amount for an unemployed person . In 2010 as I decided to job hunt again ,I was declined as I was blacklisted by CTI Financiers,I was working odd jobs till 2013 when it was removed and I could work in the financial field again, last month when I checked my credit report they had listed me again for non payment, where can I get help as this was a vacuum missold to me when I couldn't afford it
