Why are insurance companies have to be so hard to deal with. Have been calling them For like2 months to cancel my husbands car insurance sense we no longer own the car butttt no they couldn’t cancel the insurance with out talking to him and I just called and they sent me the cancellation paper to sign without needing to talk to him SMH so annoying.
