Alot of Fees out of nowhere

We used PaySimple to ACH debit customer funds on a daily basis. We were doing close to 1000 per month in debits. After years of slowly raising my fees, I realized I was paying over $3000 more per year from when I started with new fees they came up with. After transferring all of my accounts except 5 to a new processor they just terminated me today. The software is very good but, in my opinion, their slimy tactics and nonesense termination will leave a bad taste in your mouth. Just to give you an idea I went from $800 per month in fees down to $140 per month. I think that is insane.
