YES!  This is the 4th time it's happened and I cannot get onto Ebay!  

I sold an item for $10 plus postage of $9.98.  Ebay put 6.30 in my account for the payment (hence taking out the postage of $9.30 plus their fees) - then today they inform me they are taking ANOTHER $9.30 out of my bank account!!  I cannot contact them though I have tried sending a reply to this email.
