ENC Rude Consultant/ Telephone number confirmation

Hi, I am hoping I could get some help. I received a phone call from a very bizzarre consultant this even who kept talking to me in Isi Tswane (I am Zulu speaking) despite me replying in English in hopes that she would switch back to English.

Anyway, she was advising me of a debt I apparantly owe to MTN. Never have I purchased anything from. MTN. She went on to request my email address which I did advise her off. She said she would send through all the details but its been 5 hours and she has not.

I am now worried about this since I have bern a victim of fraud before.

Please confirm if this number is indeed from ENC **********
