I'm sorry to hear that.  It very well could be glitches. I know sometimes I don't even recieve IM's that people send me.

Also don't forget that some have very busy jobs. It is very easy to forget to reply once outside forces take over. 

I know it's annoying, but don't let it discourage you too much.
