Uninor / Telenor — international calls issue

Dear telenor, i am receiving too many calls from last month to my telenor number. I am requesting to you please block all the international calls from my number permanently. My number is [protected].
Please make me confident about it, i cant tolerate such activities. I am your customer since 5 years ago. Please take care of me. Stop international calls for me no matter from which number. Please do it for me and ensure me that telenor is safe.
I am getting a call from [protected]. Each and every time person focused on reading quran and whatsapp me some videos showing abusive content.
Dear telenor block such all matter pleaseeee.
