Warrant information by sms

My brother had taken a loan of 80000 before corona, after corona his situation became worse due to which he was not able to pay even his home loan or any other loan. He had to sell his home at very low cost & all remaining amount was paid to the local lenders who were harassing him much. Now after he stopped to pay he had recieved many calls & threatening from the recovery. Recently this year he get a summons letter from advocate through whatsapp & then recieved a sms every month in name of HDFC BANK about the summons being issued by court as follows : Attention!
