The response "I'm sorry our decision is final and we cannot communicate any further" that vendors give (Google, Square in this case, etc.) is nothing short of stomach-clenching maddening. Just reading it fires up rage inside me. I understand why they do it -- it's pretty clearly related to their anti-fraud / anti-spam / security systems, and I understand that by giving any further information, they're exposing those prevention measures to weakness. And I'm sure in cases of real fraud / spam / security risk, this is the right approach. But man, does it stink for everyone involved when there's a false positive (i.e. in this case). There's got to be a better way of handling this. Some sort of escalation / appeal process? (And if there isn't -- hint hint, companies that haven't gotten big enough to be immobile on this issue: Implement one.)
