Personal loan limitation act

I taken personal loan in july 2008 of 5 lakh divided in 24 month emi (26000 per month emi ) .... due to personal reason i paid 15 installment ( around 4 lakh rupees ) last emi paid on nov 2009... i received bank letter in dec 2009 by ordinary post ...after cheque bounce for loan payment .. my father also co applicant ...last year in 2016 after 7 year (last emi paid) recovery agent come asking for loan pay... he was asking for 6 lakh rupees due to interest and penalty during 7 year.... me and my father denied for that...he never come again and we never commit and reply any latter to bank ... only bank taken 4 cheque in 2008 when given loan ...my question is that can bank recover loan after 8 years or recovery agent creating gimmick that if we not pay loan then bank can sell your home via legal notice ... still i am not receving any leagal notice from court. bank given loan on account balance based not on income tax file.. because we never filed income tax return...me and my father monthly income 15k ... on that time bank offer us we thought we can utilized but we not success .. but at least we paid 15 installment 4 lakh paid 80% principal paid ... bank was icici bank saving account with icici bank and i left this city and bank i never visit this branch after last emi bounced and also i dont know what happened with my 4 cheque ...my father still live there...can bank recover loan from us 6 lakh rupess after we already paid 4 lakh in installment.
