BPTP — i am complaining against countrywide promoters private for getting my refund

Hi guys. I am the victim of the bptp faridabad plot allotment. We have applied for the plot on the name of my mother in nov 2019. The sale representative told us that in case u didnt find the plot good u can quit from the scheme and u will get the complete refund of rs 4lakhs. But that we have facing some finicial problems and fill the surender form for refund and submit all the documents for refund. Now i chasing them since 7 months for getting my refund but i didn't heard anything from them when i am sending mail they just send me copy paste reply. We havent signed and ask to refund the money. Please suggest what should i do. We havent even signed on allotment and aggrement paper. Please help me to get my money back.
