Paypal has very high fees, often ban/freeze user account and terrible contact service.
Also, i heard they often ignore transaction which related to bitcoin.
most corporations use scam tactics though Paypal appears to
be trying watever it can,
every company from real estate to telecomunications
do the scam where if u cancel a contract over the phone or send
a fax etc, they will normally ignore ur request until u demand
a return fax, email or letter of the disconnection as proof,
until then they can keep charging you for the contract and
you have no defense unless u recorded your own phone call
