Locanto — Harassments with my morphed picture

Hi Sir, i used recently Locanto Dating app. Now iam very depressed with their harassments, I received a Whatsapp video call from [protected]. Female person started to remove her dresses in the call, asked same from me, So i also removed. after that she is sending all the recorded info & asking money in order to delete, else will upload in online. Instantly i blocked her with fear. but i feel very guilty that i did a big mistake. I came from good family & i don't want to bring any bad name to my family. kindly do the helpful. Anyone please. Iam not sure, whether thy uploaded anything in Online.
