Barclays personal loan settlement

Hello all My wife has taken a personal loan of 1.24 lakh from barclays finance in 2007, she paid some EMI from ECS from her salary account and then she left that job. After the instablity of 5-6 months of new job she tried to change the account no in loan ECS but she come to know that respective Branch is closed. Then she also got busy in her life. However barclays never sent any notice or call to her to repay the same till Oct. 2016. Suddenly in Oct 2016 I got a call from fincruse finance they said that barclays is closed and they have a agreement with them to recover their amount and they ask us to deposit settlment amount of 92000 in their corpration bank account. As I haven't found any proof of their association to barclays I asked them to show their agreement with them and suddenly they started abusing us, I searched om net and found many negative reviews about them that shows they are fraud. So I started avoiding their call but now they are calling to my relatives and abusing them and asking to pay asap. Please advice can I get nil and void as bank did not even approach us in last 6-8 years and it is already shut down in India. How To deal with fincruise people.
