I want a list of colleges tha provide B.COM(hons) and the have hostel credit facility(for the fee)as well

Here are a few colleges offering B.Com (Hons) where you can also avail of hostel accommodation (at your own cost, not credit facility) :

• Banaras Hindu University (BHU), Varanasi
  Offers B.Com (Hons); hostel accommodation is available at around Rs 8,000 per year, with mess charges of approximately Rs 115 per day .

• Maulana Azad College, Kolkata
  Provides B.Com (Hons); hostel facility is available, with hostel fees of approximately Rs 2,074 per year .

If you're specifically looking for institutions that offer a hostel fee credit facility , such information isn’t commonly advertised. I’d recommend reaching out directly to college admission offices to confirm if such financial support or concession is available.
