Can't buy what I want...

I was not too happy that the insurance policy did not give me a choice where to spend my money and I was forced to go with someone online who has no local branches. However, that is just where the problems started. They do not sell Trek, a make that I am familiar and happy with. A lot of the makes they sell, I just do not know. Anyway, I chose a Bianchi cycle that looked reasonable and was told by the rep I dealt with that they did not have it in my size. He recommended a Specialized bike (£75 dearer) and said this was similar in specifications. I was prepared to accept this recommendation and ordered it online. I now get a message from sales, telling me that the items I ordered are slightly delayed from the supplier and could I wait until August 2nd. This is hardly a slight delay! Why was the bike recommended to me, when it was not in stock. I have looked at the alternatives on the site, and can not see one I like of similar specs at a price I am happy with.
