How can I proceed after my gold was auctioned without notice?

Hi , my gold has been auctioned off by rupeek and federal bank with out any notice . I used to get automated calls alone to say that the loan should be closed but no one informed about auction , on dec 24th i thought to close the loan opened rupeek app i was able to close it but i was in shortage of few thousands so i got it arranged and opened app on 26th to pay loan is no where found and i tried contacting them multiple times there was no response or details and finally on jan 13th they told me that my gold was auctioned on dec 15th only . With out any intimation well infact on dec 11th i paid interest and i tried to renew the loan but it said it got cancelled due to technical issue i still have screenshots and messages of it , how to move forward
