So I purchased an item on eBay and haven't received it yet. That was 2 weeks ago. Seller never answered my message initially, took him around 5 days claimed he was away with work then on Sunday past said the item was posted and it's still not here. I've sent him around 6 messages and only been responded to twice and am now thinking of complaining to eBay. Is there anything I should be aware of before I go down this path?
