Hi Bob, Welcome to the forum.
I sincerley hope this experience doesn't put you off the hobby.
I agree with Dave, eBay is full of cheap Chinese-clone telescopes and accessories, and it appears you may have purchased one of these. Again, you do not clarify if this was supposed to me a "new with warranty" or a "secondhand" sale. Irrespective, you should clarify this with the seller and follow up any breach of sale to eBay. Having said that, I've been through the dispute resolution process with eBay and a dubious seller and it can be exhaustive and you feel like it is not worth pursuing.
If you decide to buy another telescope, I strongly urge you to pop into the
Beginners Section here to ask as many questions as you can. You will get some beaut advice from the membership here.
Good luck.
Stephen
