I kept trying. It's almost funny. The next response was addressed to MR XXX (ie not me, some other dude!) and was about his problem...
So I replied with "what on earth is going on, my name is XXX and my problem is not XXX"
To which I got another one saying that that they are unable to respond to emails directed to this address and please can I log into my account..... (which I don't have!)!!!!!
If anyone knows the real email address of a real Pay Pal person (like, the chairman?) I'll forward them the whole chain and they can see just how incompetant their staff are!
