And they also have mine, as well as my home & mobile numbers and fax number. However they still chose to contact me via ebay messages and the polite thing to do is reply the same way if I can.

Since ebay blocked me from replying they missed the commission on the balance owing and will now miss commission from any future purchases made by this customer as he is happy to contact me directly in the future.

Their idiotic policies are forcing the exact situation they are trying to avoid.
