Idea Cellular — not receiving sms/text message

Address:

New Delhi, Delhi

I updated my idea 3g sim to idea 4g, i am unable to receive any messages from others friends, banks otp etc.
I contacted customer care of idea or idea outlet, they told me it is activated and working, although my all services is activted except messages. I can send the message but not received the message.

When i approach to outlet of idea they told to contact customer care & helpless.

I have been facing lot of inconveniences & problems due to this, i lost some faith by my regular customer.
Due to this message problem i can not do my work.
