HARASSMENT NEEDS TO BE STOPPED.

How do you stop the harassment. They keep on sending the same message on a daily basis, after I have phoned 3 days in a row to let them know they are contacting the wrong person. Thy are using up my airtime while I have a sister in ICU due to Covid. Any suggestions on how to stop them from abusing numbers. These must be the dumbest call center in the history with a combined IQ of 3. Harassment will not result in money - FAR FROM IT. I suggest people just ignore those messages - you are owing them NOTHING. Can one open a case of harassment against them?
