Westlake Finanical Harassing me

Westlake is ripping me off on a warranty worked into the loan and the warranty company has gone out-of-business. They also harass me non-stop, 3-4 times a day they call threatening me, when I am current on payments. They call every day and night. One man threatened to beat me up and ruin my life. They take more payments out of bank account, until I had to change bank accounts and they are upset that I won't give them that number. I am a very sick woman and they have called and harassed me while I was in the hospital threatening to reposses while I was in the hospital! They have called and harassed friends and family members. The list goes on, I want a lawyer but I don't know what to do.
