Airtel — offer and approach of customer care

Address:

Kannur, Kerala, 670325

Sir,
I have called customer care for the issue of my offer. I have got a message that ₹179 there will be daily 1 gb offer. But after recharge it was like 1 gb for 28 days. But when i talked to customer care 'unni maya' about this she was like why should we concerned about your benefit??. Why do you have such a custom care if there isn't any benefit for us..
Hope you will be solving my problem regarding the offer also.
