Vodafone India — vodafone threatening to stop service with just 7 days notice - I am in roaming cannot do this

Address:

Mumbai City, Maharashtra, 400071

Vodafone 's attitude towards its customers is appalling.
My number is [protected]

First it introduces this 4g sim upgrade offer, which is optional.

No where does it say that it is mandatory to get a 4g sim.

Then all of a sudden vodafone starts threatening people with messages saying that their phone service is going to be stopped if they do not upgrade to a 4g sim.

I live in chembur, mumbai. I am currently visiting family and friends in west bengal. I have received a message 2 days ago that i need to upgrade my sim to a 4g sim otherwise vodaphone will disconnect my services.

The place in westbengal where i am, there is no vodaphone store which is able to give me a replacement sim from mumbai. Besides it is unfait for vodafone to give its customers just 7 days notice. I will be back in mumbai after some months. I still have credit on my number and i need my phone to stay in touch with other people and for my day to day work.
