This below offer is exist since March-April 2013 and I registered airtel money account in March month and before loading amount into my airtel money account I called to Airtel money customer care and asked about the offer and they said max I can get 50/- for March and 50/- for April. Then I loaded 1000/- on my airtel money account and paid my postpaid airtel bill of 500/- but I was given only 25/- cash back(5%). And when I called to customer care they are saying because I registered on March month so I am eligible only for 5% but when I called to CS and even checked in website it is nowhere mentioned about registration starting date. It is just mentioned that first 2 months of registration date, customer is eligible for 10% cash back(max 50/-). This is not a good service, I am happy with airtel mobile service but airtel money is waste service and even no one is bothering on replying my mail. At the bottom I have provided my complete mail chain. They are saying they have forwarded the issue to concern team and from concern team no reply at all.
