DigOwnGrave, I have read your case. Yours is a loan scam. You must understand that if it's real loan shark loaned you real money and if you don't pay in time, they will take the risk to sent their runner to splash paint and or perform arson in order to get back their loaned money and interest. However, if it's loan scammers, I don't think they will take the risk to splash paint or perform arson as they never give you any loan at all, instead to threaten the victim who are frighten of their treats to as-tort as much money as possible. Moreover, this scammers, will not dare to step into your house as they know that every lift and 1st staircase attached with police camera can be captured and reviewed anytime by the police. This will disrupt their fruitful business and manpower if they has been identified from the CCTV camera. Love letter, this scammers can only mail to you to further threat you to make the victim frightened. Whatever threatening mail you receive, bring straight to police station and make a report. Lastly, block all unknown contacts you and your NOK received if you intent to keep using your existing number. If you want some peace, close your existing number and open a new number. Your data plan and subscription will not be affected, as it will be transferred to the new number. Before you do that, screenshot and keep all their threats as evidence from your existing old number as you will lose your whatsapp messages once you migrate to new number and re-install back whatsapp to new number. Inform your office not to entertain their calls and tell them it's a loan scam. Have you met your Investigation officer yet? Let him/her know about what is happening. Hope this helps.
