Sir,
I had referred my friend for tatasky new connection & as per the advertisement given by the company it is stating that after the successful installation of new connection through a referral from a user, the refereed user will get 300 inr cash on tatasky account. But i don't have got any cash back and the company has denied the same saying technical irregularities. As the company has the proof for the referral from my side and proof for the new connection by my friend for whom i had made the referral, the company is making false promise to the customer customer by providing fake info and for getting new customers through the existing customers. Request to take-up the case forgetting the justice to me as a customer. Attaching the proof of referral (Screenshot form tatasky app) and the advertisement given by tatasky regarding cash back for referral.
