Airtel — about balance refund..

Address:

Gurgaon, Haryana

Sir, my self robin huriyal and my mobile no is [protected]. My balance was deducted on 23 rd feb at around 10 pm for a service. I talked to airtel customer care on 24th feb at around 7 pm and they promise to refund the balance n stop the service. But they did not do so. I call them again and asked about the matter so they told that now they wont refund the balance because it more than 24 hrs of your deduction. So i asked them that i called you within 24 hours but its executive mistake why he didnt refund when he told me to do so yesterday? But they refused to refund and told that they will give feedback to their executive. I spent 5 rs to talk them for refund n 21 rs is my bal deducted. Now wat to do ha? Plz help.. Rs 21 is not a big amount but it is a reason of custo.er satisfaction.. So plz take a proper action against them..
