I do believe paypal is not a scam. But for a certain years that being established in this industry, there are many circumstances they encountered in terms of there services. And we can't blame other's why they complain, of course they are fighting for their rights that they invested in paypal. Paypal will continue to stand as long as there is client giving their trust to them. In your case, my suggestion to you is keep on trying to contact with them after they fix your concerns to them I think its time for you get away from them, so worrying will not be apply anymore.
