According to Friend Scheme of airtel there are happy hours between 3 to 5 and 11 to 8 in which you can call any airtel number at 10 paise per minute. When i call at 3:25 at noon on 30-1-09 to airtel number they charges me at 1 Rs per call, it must be 10 paise per minute.when i call to customer service and ask about there server time then he told me that it is 3:10 at noon and actual time that time is 3:45 at noon .when there is server time is wrong then there is no possibility to enter a valid timing entry.
