Complaint Review: A PLUS MANAGEMENT

I purchased an Motor Coach from A Plus Contract Management in 2015, paid APCM a deposit $10K and transportation fees. I made monthly payments to APCM for many years and I found out APCM wasn't making payments to bank in a timely manner. Jim Salder  no longer returns my calls. I've called the Attorney General in Florida and haven't heard back from her office. I've red other reports on him ripping off others owners. What can be done to stop this scam? This is FRAUD that is taking place in many states. I've paid $1068.88 for three years directly to Wells Fargo Bank. This guy shouldn't be in business.
