That's good. You should continue.

Is it just me or normal?

Yeah it appears to be normal from what I have experienced, followed closely by zero email etiquette when there is a reply. Trying to buy a product from one of the advertisers on this site, no reply after multiple attempts to email them, ultimately spent money with some one that does reply.

My email reply rates are much more successful out of Europe and north America though.

if they have a customer feedback "tell us your success story" - often goes straight to their P.R department - use that one. Worked wonders for me with a couple of them

I need to add - I phoned a company today and got an answering machine with a very nice message.
The machine asked me to leave my number and they will phone back..
Still waiting
