Vodafone India — charged extra for the internet

Address:	Mumbai City, Maharashtra, 400071
Website:	www.vodafone.com

On 22nd My internet started charging for the data i was using however the same day i received a message that last months 5 GB data has been rolled out to current month. After this I called your customer care & your executive said that I've consumed whole 20 GB data (My data limit while joining Vodafone is 20GB + 10 GB extra - Not applicable to my account yet). this is the first miscommunication done from your end.
Secondly no postpaid network charges you once you consumed your 4G data rather than that we can still use internet but in 2G speed which was also proposed me at the time of joining you. I got charged for around 500/- rs & now you my internet speed reduce to 2G for free which is ridiculous!

Today I got the messaged that we have added 20 + 10 GB internet in your plan for which i got surprised!!! but now when i called your customer care again for waive off they told me that it's 10 GB only & not 30 GB (20+10). This is the second false commitments received from your end & I do have proof of all with me (Attached as well FYR).
Even though having 100 free SMS I still got charged, why?

I WANT WAIVE OFF FOR THE EXTRA CHARGES OCCURRED or I'll not pay the bill & file a suit against you guys with all the proofs.
