I missed the call. No ,sesame left. Tried calling them and the number is no good.

they call my work all the time. when we say our speal, that we have to say when answering the phone,  they hang up.. but if we answer hello they ask to speak to a manger.. idk what they want but the 2-3 calls a day from them are driving the office mad
