[Resolved]  MTNL Broadband — free MBbs allotted are less den the plan's limit

Dear sir/madam,

As applicable from the 1st of September MTNL BROADBAND announced an increased 200 MBs for the "DSL_199_256kbps" PLAN, i.e. before that there used to be an allowed 400 MBs for the Rs 199 plan but from 1st September they increased this limit to 600 MBs.
But when i checked my account for the left MBs of the month, around 118th of this month, i got to know that i have been allotted the same 400 MBs only for the month.
Then, as usual, i complained for this on MTNL BROADBAND CUSTOMER CARE NO. 1504. The person there understood my problem but still just blamed that on other departments. When i demanded him for that department's number he didn't even give me that. Then i got that number from directory helpline and called there. But the result and attitude of those people towards solving my problem was the same, and even their way to talk wasn't humanistic and they clearly refused to do any thing in my case.
So, sir/ma'am please help me regarding this case and please grant me to have those MBs in current and future times.
Thanking you,
