HDFC limited
Change in agreed building plan

I booked a 2 BHK flat in PRAKASH APARTMENT at ASANSOL (WB) in January. HDFC approved my loan (Loan A/c No-539108488) for the flat when I submitted agreement copy and building plan in March. PRAKASH apartment is an approved project of HDFC ltd.

But the builder M/s Aniraj Enterprise secretly revised the plan in April in collusion with HDFC Kolkata. Neither HDFC nor the builder informed me and kept secret all inspection reports of my flat F-01/c at PRAKASH APARTMENT and disburse laon amount Rs.6, 71, 750/- to the builder.

In November, when I personally visited my flat, I came to know that my flat was not built as per plan I had given to HDFC. Clearly, there is a collusion between the builder and HDFC.HDFC violated RBI Rule Clause 12 (A) i, ii, iii for Home Loan Financing. I complaint to National Housing Bank, but HDFC Indore has given an ambiguous answer (copy attached).

Can I approach Consumer Forum Against HDFC and Builder. Both are from different states, so different jurisdiction. Is HDFC violated MRTP act?

Indore consumer forum told me that compalint agaist can not come under MRTP act?

Please suggest
