They started calling me around 9 pm tonight and so far the number has called me 27 times. and counting. non stop

i answered one call and it called me five times IN THAT CALL

Did you EVER consider either not answering, or leaving your phone 'off the hook'.?

Number is not valid.  Was blocked by nomo.

Now I'm getting these calls on my cell phone.

Did not answer it.  Caller ID showed out of the area call.  Apparently that was the right thing to do.
