PayPal employee problem

PayPal is big company, big company got many management problem and cause security problem for customer. First machine problem, because machine don't think like human. For example, register on PayPal account, give cellphone number, "happy hour" girls deliberately want disturb, slept with someone know computer, change phone number, after discover what "happy hour" girl did, want get correction, call PayPal support center, if using correct number call, answer machine don't get it, because correct number isn't in data center, you must use phone number "happy hour" girl changed for calling, because it is in data center, and answer machine next problem asked is "What's your SSN last four digital number?" It seem should not connect SSN with phone number "happy hour" girl changed, avoid they pirate SSN. If answering phone is human, he or she can understand your subtle problem, possibly correct phone number, solve problem. Answer machine can't think, it can't solve problem, so calling support center can't get help.
If you want send email solving problem, it say "You can't send email now". Situation is like someone deliberately don't want solve problem. Someone want to know who is "happy hour" girl?
They are some young women for asking men help them did something, for example revenging, disturbing, slept with men and get men's assistance. They are prostitutes using their sex seducing men did some crime, causing customer security problem. PayPal problem is also at pirating customer money. Bought item from eBay, payment evidence shown on Paypal APP, didn't receive item, require seller refund. PayPal send receipt claim refund amount, PayPal APP show -$45, under data described sent refund, obviously PayPal employee make mistake, if refund amount is +$45, they not only refund +$45, but also double charged -$45, customer balance reduce $90 . If customer can't discover, obviously PayPal employee got money $90 by cheat. If employee accidentally make mistake, if contact them, they should solve problem, but email can't send, call them due to "happy hour" girl change phone number and answer machine can't think, can't ccntact Service Center, their cheat crime get, if one customer they cheat and get $90, if ten or hundreds of customers they successfully cheated, how much money will they get from cheat crime. After customer get knowledge of PayPal employee cheat behavior, who dare use PayPal?
