Vodafone India — Mobile internet, less mb

Address:

New Delhi, Delhi, 110064

I am using vodafone mobile network.My no is [protected]. I usually used to recharge my net with 300mb. I recharge on 19th oct with 147rs for 375 mb which finished on 24th oct to 34 mb and same day i recharge with 255 rs for 1 gb, i got message that i got 1058 .55 mb which is valid till 20th nov . but i got message on 29th oct that i have reached 50% of the internet pack and balance i have 183.35 mb .
I call to customer care and i lodged complaint (complaint no -[protected])on 29th oct, they told they reply to me by 31st oct but they didnt call me and so i called 31st oct and again they gave me 24 hr time to response but they again didnt call me. I called today 9am to customer care and they are telling that i have used all my data and they have closed that complaint on 31st oct after they called me . but they didnt message or called me . I asked about detailed of my used data but they couldnt provide.
when i checked on my mob its showing 375 mb plan activated and i told them then they are telling its error and they refused to give my remaining balance .

183 mb is 50% of 375 mb not 1058 mb that means they have not given me 1gb .
so kindly help me to get my remaing balanc
