Nar Verification Code Not Received

I am a Nar subscriber using the number 070 8** 03 02. Until today I was regularly receiving verification codes to this number through SMS and confirming my logins, especially via WhatsApp and other applications. Today, however, I suddenly stopped receiving any verification codes at all when I enter my number and request a code. On the screen it writes a message like “verification code could not be sent, please try again”, and no SMS reaches my Nar number. At the same time, I am sure that my number is active, but I strongly suspect that someone else has gained access to my applications and this situation is seriously worrying me. I request that Nar urgently check my line, determine whether there has been any unauthorized access or intervention, and immediately secure my number so that only I can receive verification SMS and log in to my accounts. I also expect information in detail on the cause of this problem and confirmation that my number and personal data are safe.
