Sterns bank leasing Un warrant insurance due Nationwide

I have several leases with this company first I would highly say stay away from. I have never been late with any of my payments. Well at the end of the lease they stink it to you. Totally fraud what they do at the end of lease . First it all starts when you have about a year left on your lease. You get letters saying you don't have insurance on equipment they need proof . You call insurance company and they send proof then sterns keeps replying not sufficient you just keep doing this then the last payment they charge you a big insurance fee which you already had insurance which you still have proof. But then sterns says it's to late contract ended you owe it and they won't back down its really fraud . Now it's already starting on my other contracts I told them don't even start my insurance agent sent proof and my agent says they are ridiculous sent proof on the equipment before but now it's not enough information I know exactly what there doing. So main reason I'm going public is to warn others . If they try this again I'm going to get my attorney on it.
