Question G Note2 suddenly stopped making and recieving calls

My stock, unrooted Verizon Galaxy Note 2 stopped making and receiving calls this past Monday. But only calls are effected. 4G and Text are fine. Went through the usual battery of Verizon troubleshooting steps with no luck. Did the soft reset, hard reset, replaced sim, switched between LTE/CDMA & Global networks, danced on my toes, and twirled like a ballerina. Verizon said it was their network and that it thought the device was asleep. Then they said it a faulty sim. Then poor reception. And....... And..... And...... Finally today they pointed me to the nearest store to buy a new phone. Anyone else ever just have the phone stop making calls? Calls worked Sunday night and did not work Monday morning. Very Perplexing.
