I have received robo calls off and on for 6 months, sometimes multiple calls in a day. The calls stopped for about a month but have resumed. I do not have caller ID, so do not have a called from number to share. Robo call advises that they are calling from 'AmSher ' regarding a debt collection. Advised to call XXXX. I have no known debts to be collected. Out of curiosity and in an attempt to end the calls, I called the number a few months ago and got a machine ... I was provided with no information so was unable to enter a 'case number ' or agent name ... I just called again, just to check again ... Currently, their answering machine does not identify them as AmSher or any other company. Previously, the answering machine asked the callers to leave a detailed message ( I did not! ) including name and contact number. Now, the answering machine has a robo woman answer without identifying the company name, then it 'clicks ' over to a robo male like it switched lines and he says all agents are currently busy then askes you to leave a message. Very benign yet very alarming considering the company is supposed to be a collection agency and I have no known debt to be collected!
