female impersonator

A scoundrel contacted me on WhatsApp and told me a story that I am his girlfriend, that I sold him and married someone else, causing problems with my husband. He contacted many numbers and registered the number under one woman's name, but he is known to harass women anyway. When I called him, he started insulting and being rude. I am very upset with him. Does anyone have any idea what I should do? His name on Truecaller is Um Ahmed Al-Hawi, Ya Ahmed Houshi, your son Ahmed, and Darry Ali, and Kasta.
