Airtel — cheated by mr. siddhraj by giving false offer

I have been receiving call and SMS(from HP-ARTDTH) for last 10 days from[protected] by Mr. Siddharaj, Rakesh and Rahul. Message content is as below
”Gentle Reminder Ajej Recharge Karo Airtel Dth Ma Fakt Rs 1499 Ma 6 Mth + 6 Mth Free, With 25 Chanel LifeTime Free, 12 Mth Pachi 1149Ma12 Mnth FreeCall[protected]”

On call they have informed me by looking into my details that recharge with 799 and your base infinity package will automatically get connverted into Unlimited Dhamaka Offer where You will get 3 months + 3 Months free so total 6 months pack.

However, after recharging my account with 799 nothing has changed instead it is showing my balance 795. Also I got SMS from AD-AIRDTG as below
“Request for activating airtel digitalTV long duration pack could not be processed as existing pack is different from the pack recharge done. Please call[protected] [protected]”

I called up on[protected] as well as on [protected] to Mr. Siddhraj but both Mr. Siddhraj and customer care executive talked very rudely.
