This scammer calls numbers on the national do not call registry in violation of the Telephone Consumer Protection Act. They further violate the TCPA by repeatedly calling even after being told to stop calling and take the number of their lists. They call offering discounted credit card processing services, but are most likely a scam based on their telemarketing techniques. They do not provide an address or phone number when asked, instead they transfer you to hold music. This is clearly a scam. Do not provide this scammer with any personal or financial information.
