Pakistani / Indian/ Bangladeshi SCAMMER / PHISHING "call center" -   "Credit (repair/improvement) specialist" (read: scammers & crooks) services, so to speak. They are phishing for credit card numbers, social security numbers, full legal name, date of birth, current address, phone numbers at home & at work, etc. They promise 2% or no interest credit cards, upon giving them your information - SCAM, SCAM, SCAM!!!!
PS These phone numbers, such as 912-373-7936 are fake (spoofed) and are created by special equipment. Caller ID spoofing is the practice of causing the telephone network to indicate to the receiver of a call that the originator of the call is a station other than the true originating station. For example, a Caller ID display might display a phone number different from that of the telephone from which the call was placed. Caller ID spoofing equipment is available to people with a specialized digital connection to the telephone company, called an ISDN PRI circuit. Crooks, shady collection agencies, law-enforcement officials, and private investigators have used the practice.
