Just Dial Ltd - Misselling done by the company

Last month I have freely-listed on Justdial to get business. After listing I was getting various calls on paid membership. On *nd April ****, I was offered a plan named VFL.
See the misselling -
*. Product is verified lifetime listing. I got contract listing for ** years.
*. The product offered was **,*** + GST **% total is **, ***. I was not convinced. So they gave me an EMI option in which interest will be beared by Justdial. So, I assumed I have to repay **, *** and interest on such cost are paid by Justdial. I was assured I am paying only capital and not interest. Now, the wonder is the interest at **% component, they included in the amount. So, on the invoice, the net value of the product is *, *** and not **,***. Interest amount and GST amount is deducted from **, ***. On *th April I received a copy of contract and invoice.
*. On *th April, rm asked me to activate the contract. I asked him I am out of town for * days make it on *th April.
*. Even after confirming me they activate on *th April. They activated on *th April itself.
*. On *th I raised the issues. I asked what is capital payback to rm Akshay, he said I don't understand that. The contract is an arrangement where we are reducing price what is in it for you. Why you are having an issue if we have lowered the price to show in accounts. The concern is they only sell the product don't know the working of the product. They were saying I am not getting their point. I asked to cancel the contract. Whats their reply "contract cannot be cancelled" I asked them have they stated at first that contract cannot be cancelled. The operations team said they will get back to me.
*. On *th April, I again contacted, no one to answer and the same reply contract cannot be cancelled, we can only solve the issue what I was facing. They said the concerned team will get back to me *. On **th April, I again raised the call, still the same answer. I called up sales person Jabbir shaikh and relationship person Akshay Panchal who convinced me to execute the contract. He didn't pick up mobiles and responded via SMS they will call back.
At the start of the contract, I am facing issues. I wanted to cancel the contract and request for money back **,*** which I have paid via credit card against an EMI option. All my details are there on the copy of the bill enclosed herewith. Need refund, fraudulent activities faced from Justdial. Looking for resolution.
