I have dealt with ebay ony 3 times. The 1st time, I was not delivered an item on COD saying that my area doesnot fall under the COD whereas I received mails from ebay promoting COD. I almost forgot the issue but I had to forward the case to the ebay consumer court, which seemed to favor ebay.
The 2nd time, last month, I bought an Antivirus (Bitdefender) but the License key was already in use, which I confirmed from Bitdefender. I raised a Guarantee Claim and I agreed to accept EBay coupon like a FOOL.
Lastly, recently, I was surfing for some products and come across Night Vision Goggles. The Seller sent me an ordinary white goggles, worth 50-100 bucks in the local market. I had to raise Guarantee Claim again, which is being refunded no, ofcourse not in the form of ebay coupons.
Overall, my feedback is completely negative and my last transaction with ebay.
