I would not recommend First Data to anyone. They are difficult to deal with, and charge huge fees.
I cancelled my services and they charged me $60 for one transaction in the month of September!!!!!! I called to complain about this and they told me that was the fee for the month and one transaction of less than $50. This is amazing - what a rip-off!
I don't know what else to say about these people to extend my rant to the minimum 100 words other than don't sign up with them. They cost me quite a bit of money!
