Can you please advise if the sentence is correct:
I have been waiting for the request from you as usually, but did not get any.
The context is:
Every half a year a person sends me a letter, where he asks to advise the quality of books I need. But this time he did not ask me.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
