Karthis Pvt Ltd — Scam and asking to pay the loan which haven't taken

I am receiving the messages from AD-KARCOM, KARTHIS PVT LTD saying that I have taken the loan and I have to repay It. For to be sure I haven't heard any of the app names till now nor taken any loans from these types of 3rd party applications. They have also sent me different messages on whatsapp saying that I have to make the payment or they will Inform my family. Please help me with this...as soon as possible.
