Thanks for the suggestion spuds but I have made a point of not linking Paypal to my Ebay account. The payment was not to Ebay. I have posted this before but probably 2yrs or so back. tried searching for it to no avail. Someone told me how to sort it and it was easy if you know how.
Thanks to all, found it at last, it is a Paypal setting
"My pre approved payments" where you have to change the setting to inactive.
I remembered as soon as I saw it. I don't know how they can make
it active in the first place without my permission.
Ebay does it also to collect their fees which I don't mind.
It will be written in my spanking new 2015 diary for future reference should it occur again.
