AppStar Financial First American Payments, Merimac Leasing Lied, Mislead, and Charged Hidden Fees San Diego CA

In May of 2018 AppStar Rep. Robert M. contacted me Charlton M. at my business and attempted to sale me a credit card machine when I declined the sale, Robert M. then contacted his Supervisor who recorded the conversation, stating that I could terminate the agreement at anytime without a cancellation fee and offered me a tremendous discount. 

I was mislead by Robert M., AppStar, Merimac and First American Payment.  After 3 months I noticed an unreasonable amount of fees and charges coming out of my bank account.  I then sent  back their credit card machine and blocked them from my bank account.  I was then harrassed by their collections department saying I owed them a huge cancellation fee, which I didn't. 

In March 2019 they filed a collection on my personal credit report, which I was never advised nor did I ever believe that I would be a Personal Guarantor on the agreement.  How does a company have the right to lie, mislead, and ruin ones credit, who doesn't owe them?  How does a company have a A+ rating with the Better Business Bureau, when they have over 64 negative complaints against them within a 3 year span?
