hi,
This is eBay Guru here, giving hand on experienced advices.
eBay is very good platform, stop bashing them and educate yourself to their policies. go through this step by step list:
1. after seven days of any sell which doesn't realises [means buyer dont pay for it] send an unpaid item disput to the buyer through eBay.
2. wait for the buyers responce, if he is a fake buyer or he dont want to pay, he will not respond to it.
3. after another week you can claim the final value fee credit from the eBay people, it is just a clic away, you dont have to write anything to anyone to claim final value fee.
4. now you can relist the item.
Still have confusion, search for ebay guru on discussion board and write there.
