Query: missing parts

No user manual in the package, which appeared to have been previously opened. Amazon said they'd ship another unit out, but I'd have to wait 7 days. I paid to get the original thing shipped quickly, but Amazon didn't seem to care. Amazon said it's due to the July fourth holiday. I said fine, overnight it and I'll get on Monday. They said no. I've had decent luck with Amazon in the past, but apparently customer service is no longer a priority. Sorry to say this will be my last transaction with Amazon.
