It's been my unfortunate experience that anytime a vendor makes payment only possible via Google Pay or converting good cash to a specific named type cash, particularly those that have scratch-off activation/registration numbers (yeah, the ones that repeatedly state do not reveal this number to anyone) is TOTALLY BOGUS.
Another is the " I'll send a representative with a check as I'm at work (or traveling abroad, etc.), and, oh yes, did I mention the check is already made out and I added an extra amount for you; just deposit this certified check in your account and then I'll link up with you, blah, blah, blah..." Then, when this phony, but artfully contrived, certified check is deposited your bank posits the stated funds in your acccount, you spend some against this amount, the vendor/seller/scammer "sends his representative (different this time with yet another imaginative fiction as to why he or she cannot come themselves) to collect the "change" from the earlier transaction and you think all is good. Until that is, your bank sends a notice that the check wasn't good after all and you're now overdrawn by $3123.26 as a result. A tip-off is when the scammer cannot remember what it is you're selling and uses the term "your item". I'm tempted to attach a photo of a check like this that the FBI need seeing (I tried, but they never gave any way for me to get it too them).
Yet another experience suggests using credit only and never debit on bank cards. Your bank will stop and or challenge the transaction and seize the funds from their bank and return them to you for up to 90 days in some places and cases. Not so using debit; that money is gone and not redeemable within a week. This common ploy is usually a business strategy of mistakes made good--for the receiver of the money only--and requires months of involvement with attorneys (usually your banks'), the loss of your money for, maybe years (statute usually is two years), etc. More than pesky for sure. Then there's the waiver of litigation in lieu of arbitration; insurance companies, IPs', Big Business, contractors, even so-called "Unions" are famous for dodging ownership of their acts and hanging the damages on the unwitting consumer. Get used to hearing the terms "oversight", "I don't recall", "I don't remember that", and the too-often used; "oh sorry, he doesn't work here anymore..." All made legit by "the color of their collar." If it's white it's right; if blue it's you we screw...
But, just think, without these crooks running scams and loose in the streets there'd be so many unemployed. You know, prison guards, federal agents, police departments, psychiatrists, podiatrists, and prognostologists, phrenologists, insurance and vacuum cleaner sales people, pimps, etc. Keeps life lively and, well, whatever...
