Paypal also has support (call,email) used them for refunds and changes on account.

Having had a recent experience with that, their "support" is utterly incompetent. Made a donation to a charitable organization (same one I've made in a previous year), PayPal reversed it without giving any reason, I contacted their support trying to find out why, and several hours later they could tell me nothing more than what the website said: that it was rejected and no reason was given, and I should try using some other method to make the transaction. (They also referred me to an email address for another department, who had no phone number, and that email produced no answer for a week, after which they gave the same non-answer.)

I think maybe payers are the product here not customers.

I used to think the horror stories about PayPal were mostly from sellers, and that they at least went out of their way to do well by buyers. This "support" experience demonstrated otherwise; now I just think they have awful support across the board.

I haven't seen the refund one. Do you have it? All I could see is the ticket system where issues are closed by support rather than user.

Should be able to try for a refund on a payment until 6 months old.
