Who called from 2048099839

Got a call from this number when I called back said cannot complete the call. Any ideas?

CALLED AT 3:11 AM    DID NOT ANSWER

Frequent spam caller. Never leaves a message. Should be shut down.

Phone rings. I stop whatever I am doing. It stops before I can pick up the receiver. No sound. I check my voice mail. No message left for me.
I am p..d-off and make myself another espresso. Will stick to the rule that a caller who wants to remain anonymous is not worthy of anyone's time.

Numerous nuisance calls
