I have been using them for several months and I get my money on time and they answer my emails with in 24 hours except during internext when I emailed everyone there because of the rumors and some answered the rest answered later
I do not know if they will have problems with visa they seem to be very picky in how they approve sellers using their services
I got burned by globill for a lot of money and paypal froze my accounts because of one complaining competitor even though the complaint was false (I did comply with paypal's tos changes) and they did reinstate my account.
I like probilling but I am going to diversify my access to cc billing solutions to include everyone in existance and I am going to have pages standing by to replace pages with billing companies that go out of business.
I am talking to my bank about a payment solution that provides a way for the customer to enter the bank and make the payment direct to my account using cash check or credit card no merchant account required. (So far I collected over $4,000 USD using this method.)
I like
http://probilling.com but I will not reccomend them or any cc billing solution to anyone.
