T24 Mobile — against making mobile no. unavailable (blocked) without prior notice.

Address:

lucknow, Lucknow, Uttar Pradesh, 226024

It's been more than 3 months my phone number is not active.
I am not able to call anyone because it doesn't ring and gets disconnected in 1 to 2seconds. Also when i am calling on my t24 mobile number with some other phone its says that "the number you are calling is temporarily out of service. Please try later."
I have many accounts (Phonep, flipkart etc) linked to it and now i am in a situation that i have no access to any of the accounts stated above because all these require otp to login and whenever i try i cannot get that otp.
So it's creating great difficulty and i want you to provide me all the details of my mobile no. Deactivation and immediately take some procedure to make my number active.
