Based on the provided information, it appears that the caller with the number +27120550818 is likely involved in suspicious activities, as they refused to disclose the purpose of the call and instead tried to extract personal information from the recipient. The caller's behavior, such as repeating themselves and insisting on confirming the recipient's date of birth, can be seen as aggressive and manipulative. The fact that they hung up when their demands were not met further supports this assessment.
The person on the line wouldn't disclose why they called, kept repeating themselves, demanded I confirm my birthdate, and then hung up when I refused.
