Don't understand question marks at the end of sentences that aren't questions. Are you making statements or asking questions?
Check the plug is properly inserted and nothing has happened to it to make it loose.
Have you checked there is power coming out of the wall outlet? Maybe plug in a lamp.
If there IS power at the outlet, then check the cable and the plug. Are they damaged? If it is a rewire-able plug, is the cable secure?
If there isn't power at the outlet, check the breaker in the fuse box. If it has tripped you need to think about what made it trip. The favourite would be a heater fault but that isn't guaranteed.
Its then just a case of eliminating each link in the chain
