What to do in small claims case when plaintiff was negligent, violation of FLDUTPA, and failure to fix defective mobility lift - also improper procedu

I am Pro Se in small claims case, though plaintiff was negligent in not fixing problems w/lift from day 1, and several times failed to fix until lift completely broke...they have billed for services not told any costs in advance...and since my federal health insurance paid 80%, I have an alleged 20% cost share, but, the company failed to provide a loaner vehicle, for what they said would be 3-4 days to install, but, turned into 3 weeks, with them authorizing me to get a rental car, and deduct cost from my copay/cost share. Lift problematic from day 1, they failed to fix, I had to buy another vehicle, with no lift, and was returned to homebound status.. They also damaged my van, and illegally towed it (by non-licensed tow operator - one of their employees), and failed to communicate with me. They billed for things without advance notice of cost, or estimates in writing. They forged my signature on Health Claim Submission Form. I am military dependent.
