BPTP — flat n205 bptp park elite premium exorbitant escalation of costs

Address: 110001

Dear Sir/ Madam,
I had booked a flat with BPTP (Park Elite Premium Sector 86 Faridabad).
The Builder has delayed the project by Two years and is charging and escalation Cost of 8 Lac 31 Thousand Rupees, While the Basic Selling Price is Just 28 lac Rupees. This is an escalation of cost by almost 30% of the BSP.
I think this is totally unfair on part of the builder.
(The Flat was supposed to be 1305 sq ft but now the area as claimed is 1397sq ft, Still it nowhere justifies the escalation).
Now I want that :
A. Either the buyer should waive off the escalation charges
B. Refund the money that I have already paid (34 lac 65 Thousand) along with interest.
Yours Sincerely
Ambarish Srivastava
