How does a seller get my telephone number

[milmil49]

I've had a seller print my full private home number on a parcel posted to me.  How the heck has she found my telephone number.  Ebay told me it was on an invoice from PayPal but PayPal have a different number to eBay.  How has a seller found it as I can't find numbers anywhere?

Sorry I have removed the link as it shows my number. Will try a different way.

This is one place where it can be found if you have authorised it.
