Two person on same pan

Hello and namastae, my name is shiv, i have a query regarding PAN for HUF we had PAN allotted to us in 2005. when we see details for our PAN it shows someone else's name. we have even contacted department and they asked us to file manual return. we have refund of 9800 something to claim. also, we are supposed to provide PAN to bank but bank denies it being PAN belonging to some other HUF. please help me in solving this issue. i want new PAN but also refund for it. i am worried that i cannot surrender it as it might affect other party operating on it. Thanks Regards Shiv
