Paycor stealing money, unprofessionalism.

In my experience, overcharged for all companies for over a year. trusted them so I never checked my invoices. when I noticed back last November of all the extra charges, quickly called to see what was going on. they said they'll ask them to reimburse me but, in my opinion, they never did. when they setup my account, they said I didn't need anything else but was still charged an additional $100 a month for missing tax info but, in my experience, they said everything was ok.
I talked to 5 different people including a supervisor to get everything fixed but, in my experience, he told me I was wrong and didn't believe me. product is great but the customer service is what lost me. I have multiple stores that they're losing because of this. I wished for better customer service. In my opinion, they blamed me rather than listening to why I was being charged all of those extra fees. been there since 2018 and not sure what what has happened to Paycor in the past year. I would highly recommend another payroll company speaking from a long term client of theirs that, in my opinion, they just basically stole money from and then blamed me. I think that is very unprofessional. great before but not sure what happened.
