This Company is scam. Called in to terminate the account on August 2019, until now ( Feb 2020 ) they still charge monthly fee. When we call in to complain they said they can't find the merchant number on their system,even it is listed on the statement they mail out. Trying to reach out to supervisor or manager,but got a feeling this will be a long deal to go.
Good luck dealing with this company.

Spoke to Sales Manager, and promised that the account will be promised. Until today, April of 2020 still got a statement coming in.. Finding a lawyer to get them terminate this account now ( Of course they will pay my lawyer fee,i'll make sure of that )
