Poor service

I have a very poor experience with rain, I wrote an email advising them on incorrect billing, a consultant call me trying to explain why I should use service that am not using and I advise him it is noisy where I am as I was in the shop,

he then insisted to talk and he’s not willing to address my issue on email, he was so arrogant and rude

I have downgraded to limited service of 260 from unlimited of 499 downgraded on February and kept on paying 499 till date ..
