Call blocker might be of some help. Also don't pick up on numbers you do not recognize, or where there are caller IDs that seem odd. Or where there is no caller ID. There’s no way to stop the calls from being initiated.
This is an unprofessional call center, with caller who speak very poor English. They want to offer a loan to people. Then they expect you to deposit the loan, you pull the money back out and send it to the company. The is "allegedly" will boost your score. ALL A SCAM... BEWARE!!!!!. You cannot call the number back. When you do not accept, they start calling back with obscenities and unprofessionalism!!
Horrible call...asked for the wrong person, told them that person was not at the number and to put me on the "Do Not Call" list. They used profanities and called me a b&^%$ and that they weren't going to put me on the DNC list. Finally hung up and blocked the number. Unfortunately, appears they have spoofed a perfectly good number...so they stole someone's number and that person most likely had to change/cancel their number. These folks had a foreign accent and had absolutely no respect for the rule of law.
