Ebay works like this.
You buy something.
If it doesn't arrive in time (by the estimated date of arrival shown in the ad) or if it is faulty or not as described in the ad in some way, you open an ebay claim.
You have to do that within 30 days of the estimated arrival date.
You don't negotiate with the seller.
You don't pay to return the item (if the seller wants it back, they pay for a postage label)
Some sellers, if you contact them, will mess you around in order to lull you into waiting & not opening a claim. They know if they can scam you into waiting over the 30 day mark, you may have no way of getting a refund. The fact you only have a feedback of 1 makes you look new so they hope you won't have read up on the terms & conditions etc or know how to make a claim. In your case, they were right.
You can contact ebay chat help. You can tell them the story-faulty camera, seller promised help, etc. Get them to check your messages. You are outside the 30 day window but just say you believe the selelr deliberately tried to scam you into waiting. You probably won't get anywhere although I have read of rare instances where ebay did step in and refund the buyer, so it is worth a try.
If that doesn't work, try a bank chargeback.
In future, just as a general guide, try to buy from sellers regsietred in Australia.
Read up on how to open ebay claims if you ever need to.
And if you read of products with warranties, be aware that no matter what an ad says, there are rarely any genuine warranties on things bought via ebay so avoid things like phones, cameras etc from random sellers.
