Thunder Cameras they thought all customers are stupid Internet

Thunder Cameras listed a 10% discount on the Canon 70-200 mm F4 L IS USM lens which made their price $100 below Amazon.  I ordered the lens through internet last night.  This morning, Thunder Cameras emailed me and asked me to call them to confirm my order.  I called.  The very first question after they got my order number was "hey, do you have a filter?"  That was totally irrelevant to the confirmation of my order.  I said I already had one.  They kept asking what I had, I said B&W 67mm, and I thought I would deliver a message to them with my answer that I was not a novice on lens.  More questions on accessories followed, again totally irrelevant to my order.  Turned out,  I just wanted my lens and nothing more.  The last question they asked, " what camera do you use?"  I said Canon T2i.  Ah, here they were getting to it.  They said, the lens I ordered was not made for digital camera (???!!!) because what I really needed was another lens, which turned out to have identical model name to the one I ordered, but made of steel ring (ha ha!), that's what I needed according to them.  And the price?  $250 more than my order.  I guessed they just didn't want to sell me the lens at a good price as there was nothing more I would order from them.  So I said "please put my order on hold and I will call you back."  They said no, I either ordered on spot, paid the price, or not.  Fine, I cancelled my order.  I went back to Amazon to order my lens, the sit I can always trust.  This is my first time and the very last time dealing with Thunder Cameras.
