Have no idea. the number keeps calling but never leaves a message.

My daughter received a call on her cell from someone at this number saying she was texting "an old lady dirty words" when in fact she has not been. Caller said they were from AT&T but when I called the number it says that they are experiencing technical difficulties and can not service the call and to please try back. Told daughter to give me the phone next time as the caller threatened to file charges. I have all of her text messages and phone calls monitored so I know for a fact this call was crap.
