Core Payment Solutions

I'm not sure yet whether the company is legitimate or not. I'm trying to find out something about them. It's involved with selling credit card swiping for stores, gas stations, restaurants, etc. etc. What has aroused my suspicions are:

1) there is a non refundable fee of $150 to participate which, unfortunately , I have already paid;

2) whenever I call their 800 number (1-800-303-0876 begin_of_the_skype_highlighting              1-800-303-0876      end_of_the_skype_highlightin, irrespective of the time of day, I get a message to call during business hours.

Weird. Do you have any information about them? I'm afraid I shall probably have to kiss my 150 bucks goodbye.
