Sooo many helpful replies to my comment. 

Please...Please let me be on when one of you 'helpful' people suffer the same shocking attitudes/results from both ebay.com and this community. I too will have some 'helpful' suggestions.

1stly.. I am a buyer.... so ebay.com only 'concerns' being for 'buyers' as apposed to 'sellers' is a moot point!

2ndly.. ebay.com's 'complaints'/comments section is solely for ebays' benefit. They do not respond, address or engage with its members, buyers or sellers. All ebay does is direct you to a previously populated bland suggestion that you take the matter up with the seller.

3rdly... There a lots of comments suggesting that, as I agreed upon joining and continue to  engage with the platform to the terms set by ebay is disingenuous!

No agreement is viable if the choices are: Take it or Leave it.

IMHO If you make money from your customers, you have a responsibility to address any issues that arise from said interaction.

4thly Mayhap I was not clear enough about my issue. I made a expensive purchase on ebay, (making any issue arising from that transaction a matter for ebay to address) waited patiently for the item to arrive and finding that 10 days had passed without the paid for items arrival, contacted the seller, (as 'suggested' by ebay) to raise the matter. 

I waited a further 5 days without reply.

It was at this point I contacted ebay 'support' only to discover that my original message (made thru ebay's messaging system) had been deleted!!  Seriously!! Not read or adjucated. Just deleted!

On respectfully requesting some explanation and assistance, I received a stock standard auto reply informing me that, because I used an un-official email address (what the hell????) ebay was 'protecting' its members from possible fraudulent contact. (Really??? what they meant is protecting their own income stream) 

I have no idea what they meant by that. I cannot think how ebay determines what an 'un-official' email address is or what it has to do with this matter. (Note here, I was using the same (only) email address I have used since joining this platform in 1995)

But what I do know... ebay has an obligation to inform me that they were restricting contact with the seller and why. To provide reasoning: so as to protect us all.................. Really?? Equally they have a responsibility to address any and all issues stemming from or relating to this matter.

What actually happened, what brought me to this forum (beyond a unrealistic assumption that I might find, if not support, at least an cadre willing to listen.) was my indignation that on trying to contact ebay for an explanation/suggestion of how I was now expected to resolve my situation.  I was $1000+ out of pocket, had no avenue to contact with the seller and nothing but an auto-reply with unhelpful assistance from ebay.  

ebay'a reply was fatuous in the extreme. It simply suggested that I take the matter up with the seller!! 

If I was unsuccessful, in a further 6 days, I could contact ebay and they would address the matter then...

And forum members here, as shown by the replies to my post, suggest I just suck it up!!!

Thanks for all the input
