They raised my mobile home insurance from 571 to 876. I have had them 5 years, and never placed a claim. They say it's because my credit rating went down. So, it's obvious this company PREYS ON PEOPLE WHO HAVE BEEN NEGATIVELY AFFECTED BY THE PANDEMIC. Explain how my credit rating affects my annual payment? Are they accusing me of being more likely to make a false claim because I have less money?. This is a prime example of how people with less means are kept down by powerful, wealthy companies.
