The creepy stalkers and scammers our india has

so i was scrolling on insta when a message popped up from an unknown saying that he can make beautiful dresses as he had a company. I asked that why he specificly messaged me so he answered that my sister gavee the no. I talked to her and she requested me to get a dress made for her... he took all the sizes and inches and said that I have to pay 50%fadvance payment.. I stutered but then agreed. but the price was ₹7500iin advance payment and it was not even looking like an official store so I denied. after few days the same no. started to send messages to my sister even sending exclipt images of his body... she blocked the no. and we gave this no. to the cyber police please don't ever mesage back or reply to any s suspicious messages without verifying🙏
