Vodafone India — Unnecessary charge of bill

This is with regards to my bill dated 5th March 2015 for my number [protected] where I am charged for d2c_mazaa_99 twice i.e. Rs. 198. I really dont know what this d2c_mazaa_99 is. Even if i had browsed it than the volume o[censored]sage would reflect in the bill which is showing as 0.00. This means I am being charged fraudulently by Vodafone, or may be it is because I have ported out. I had already cleared the payment of Rs. 550/- which was well enough for settlement of dues with vodafone, but just because of this Rs. 198/- for d2c_mazaa_99 I am charged high. Please rectify this bill and settle the payment. I do not want to encounter any issues arising there in for the future.
