Actually you can file a case against him, report him to the police station, check mo kung taga san siya. Alam mo ang mga ganyang tao kung bina bad mouth ka just to bully or lets say na para lang maipagmalaki nila na kinakaya kaya ka nila not knowing you background is a big mistake. Pag aksayahan mo siya oras, kung nasabi niya sayo yan eh let him taste his own medicine.

Context po? Out of the blue ba sya nagchat ng ganan? Haha
