Airtel — expiry of plans in 7 days instead of 28 days

Address:

700116

Sir/madam,
On 10/04/2018 i got a sms from you about unlimited calls & 100 sms per day for 28 days with rs 93 recharge. On the same day i recharge rs 93/- & got approval sms from you with the plan details & validity of 28 days. But yesterday, 17/04/2018 i got some smss from you saying the plan would expired within few hours (Midnight). Then i call your call center & customer executive told the offer was for only 7 days, not for 28 days & she was unable to help me out. I was further astonished that, at midnight the plan really expired & my main-balance also reduced significantly. So please do the needful & reinstall the above plan for the remaining 21 days & also reimburse the main-balance which was deducted by you at last midnight. Looking for your quick or positive response. Elsewhere i have to lodge complaint to trai, with all the supporting sms of your approval of the above mentioned plan.
Thanking you.
