Just be glad your number is not being used as the spoofed number. Had this happen to a coworker. He was getting hundreds of calls, voicemails and texts from people wondering why he was calling/pranking them. I assume some people just saw a missed call and were curious or have a business reason for returning missed call. But its amazing how many people don't understand what was really happening, including people angry with him. it's gradually died down over a few weeks. Carrier support line implied there is nothing they can do.
