Mtk Services — mtk services - fraud company - charging extra fine and not cancelling the agreement

Address:

B9 Vasant park,Dhule road Aurangabad 424001, Maharashtra, India, Aurangabad, Maharashtra

I received a call from mtk services on 23rd july on around 4.00 pm and they convinced me to do their job within 5 minutes and i was under their trap. Within 30 minutes they hurriedly asked for my aadhaar card details and sent me agreement copy and acceptance letter without my consent.
Later i found out that the company runs scam all over india and is a fraud company. This was the biggest mistake on my part. I should have checked before only. Soon i called but the number was switched off.
Next day i asked for cancellation they said we cant cancel u have to pay 7000 fine on 11th day.
Please help please.
I don't want to do their work and i don't want to pay the fine either for such fraud company.
