This is a number if anyone had ordered something out of the country. Its a service that double checks the charges before they apply to your credit/debit account. You would have to order something either overseas or out of country. They dont just call out of the blue. You posted your number somewhere or somehow. But once they have your number they will keep calling. Your best bet is to answer it and tell them you canceled that order. They will stop.
It is a number from Pinger.com,
We filed a complaint with Pinger.com and requested that they advise holder
of this number to stop calling our business, maybe if they receive complaints
they will advise this caller to stop.
