I keep getting calls around midnight that seem to come from a fax machine. Starts around midnight then it continues every 2 minutes. It's incredibly annoying. I've tried calling the number but it rings out. The only thing I can do is unplug my phone! It's relentless, if I don't unplug my phone it keeps happening, which is annoying at the best of times, but since this only happens after midnight it's unbelievably cruel and horrible.
