Transunion doesn't care about its consumers

Am not happy with this rating agency,a few weeks ago my credit score was very healthy,until a ceqrtain account handed over by Homechoice and I lost over 100 points,how the hell is that possible,well I settled the so called account and my credit score was revised by adding only 30 points,how on earth do they come to such,they dont give clients benefit of the doubt because i tried for the whole of December 2021 including January 2022 to settle that account with Homechoice but I was sent from pillar to post without assistance until the debt crept on my healthly credit report with some debt collection company,please expain to me how i ****en lost so many points in one go and even after i settled the ****ed up account i only regain 30 points instead of the flippong 100
