Paypal kept blocking the transaction even though it was just a simple person to person transfer. I was on chat with their support for nearly an hour. The person kept describing some black box of a security system that, for security purposes, no one manages or can see why transactions get flagged. I asked multiple times to speak to a manager or someone on the security team and was told consistently that managers won't have more info and there literally isn't a security team...
Needless to say I haven't used them since and will do everything I can to avoid it. I have no problem if a flag is errantly raised on a normal transaction, but to say they literally don't have a security team is mind boggling.
