Alliance Research — fraudsters and liars

Akash from alliance research called me for providing calls on index options and had told me that he will be providing verbal support and if there is any losses he told me that the losses will be refunded. I paid them ₹3500 for which they agreed to provide 4-5 calls initially and they told me to pay the remaining amount on an installment basis. They provided only 1 call and kept on calling me to pay the remaining amount for future calls. I told them i will pay only the next installment of ₹1500 for which he agreed to provide calls for 2 days, after payment is done he is telling me to pay the full amount so that he can provide calls. They are unfit to keep up their words. He told me that the package is ₹10500 per month but i got a mail from alliance research that the package pricing is only ₹6500 per month. After paying the entire amount (₹15600) they persisted me to make payment of ₹15, 000 again. When i told mr. Akash of alliance research that i don't want that package and the package which i have chosen is sufficient, he is telling me that he is holding my services because i refused to take that package. When i told him i don't want to pay, he stopped giving services. After complaining in the forum he warned me that he will give only calls which make you lose money and telling your demat will be empty within a week. After incurring losses, he has stopped calling me and they are not refunding my money.
