Dear gingerly_in1,
As of now we are not facing any problems with ICICI Bank.com.
We request you to check the status of your transaction in My eBay. You can confirm your payment to be successful if the Rs. icon is highlighted.
Still if you any concerns you can write to us at Contact Us http://pages.ebay.in/help/contact_us/_base/index.html
You can click on PaisaPay & select "Buying with PaisaPay" in first tier & "Payment made but showing as Pending" in the second tier. Our Customer support will look at it and respond accordingly.
Regards,
Huzaffa
