Exactly who are the owners of &quot;Cardholder Services&quot;, or &quot;Account Services&quot; or that company that vaguely implies they&#x27;re from Microsoft Tech Support?<p>How can I complain? Because I have a load of complaints for each of those companies, and I want to turn them in to the FCC for spoofing their Caller ID, which is illegal.<p>No?  Crickets?<p>The sole and only weapon we have is to waste the time of the call center people. In at least some of the &quot;Rachel from Cardholder Services&quot; calls, the call center people are in on the scam - they collect credit card number, last 4 of social, CVV and ZIP code of billing address, which is more than enough to use the credit card number without the cardholder&#x27;s knowledge. In summary, they deserve what they get, and they know it.
