Hello Gihan,
Thank you for using Microsoft products and posting to the community.
We fully understand the inconvenience the issue has caused and that the current situation can be frustrating. However, because home security issues involve private account information, we do not deal with such issues in this open forum to avoid personal privacy leaks.
If it is convenient, I would like you to share with me the incident number of the Microsoft support person you contacted in real time earlier and I will submit and feedback the situation through internal channels and they should continue to assist you with the issue or direct you to the right department.
Also, I would like to know if you contacted the support person through the steps in the image below.

Your understanding is highly appreciated! Hope you are keeping safe and well.
Sincerely
Mavis - MSFT | Microsoft Community Support Specialist
