They need to stop calling me when you answer noone is there and when you call back rings once and goes to busy signal

I'm not interested in whoever this is!

Stop calling

Just received a call from this number.  Said I inquired about furthering my education.  Hm, don't think so, I just turned 66 and am looking so forward to retirement.  Told him not to call again, he is a pest……..these flippin' people make me sick.  I have been sick with the flu all week, so not in the mood for this bs.  Please stop the calls………….

Call 2 time  and just hang up
