If you ask for a call back & was ignored then forget about the guy.
well I'll stay but just give it time and see what happens from there ...if he does not act towards you them You ask him did he get your call if not it's up to you to leave it or just deal with it
depends was it to a mobile cell phone? He prob didnt have cred to check, so yep stay, then again if its to homeline, there could be all sorts o reason, was going to return call but power cut off? Did u let him know it was u? Has e bein home yet? He could be stil at hz parents perhaps?. Confront him first, but stil stay. Its not that big of a deal.
