Airtel — call restriction on unlimited pack

Hello sir, this is dr. Jayavel. My prepaid airtel mobile number is [protected]. I had recharged rs 399 pack on 22 july 2017 and my pack expires on 13 october 2017. The pack was mentioned before i recharge was
Rs399=84gb (1gb/day on all h/s)+unlimited calls (Loc+std) 84days.

On 09 september 10.20 p. M my call was disconnected and 4 rs was charged for the call.
I contacted ur customer care and he replied as i hav crossed 250 minutes of daily limit of call duration, i again asked that i had a pack o[censored]nlimited calls, he again replied that it is a pack that saying as unlimited calls but actually it is a restricted maximum 250 minutes per day, 1000 minutes per week pack & told terms & conditions apply. You never let me know ur terms and conditions, then y you are advertising as unlimited pack, i was already using jio which is purely a unlimited pack which is giving far better than yours. What you are advertising is surely wrong. Please take step.
