Business owner

A man called asked for someone who's out offered to assist them due to that person being gone for a long period of time. FYI they did not use their correct name but their Alias which we have established for spam detection. He did not want assistance said they'd call later (assumed when this person returned in few weeks) no message left. Within 6 hours same number called this time a woman different spiel asking for a person in charge of phone lines told her don't we don't transfer unless you have a name. She then magically had a name! She used the name the man used told them there is no person with that name here and I ended the call. Spam don't waste your time, has no respect for your time! I told them they aren't here and aren't going to be here for quite some time on the first call. Very rude they interrupt my day with another call during my busy work day after establishing they aren't going to magically reappear in a few hours. Obviously did not believe me so don't waste your breath with these people. Not sure what service google didn't show much hope this helps others
