Last year we were really struggling financially and a good friend of DH insisted on lending us some money to get out of the trouble we were in. DH made sure that a proper loan agreement was set out and signed, and he has been paying this guy back every single month. Now the guy's dad has found out that he lent him money and has sent us a really threatening letter through the post today. It says: "£1500 and you're getting off lightly. I want payment in full by 1st May. Payment will be made to me personally. **** is not to know I have contacted you. You have the option to ignore this, should you choose that option I will sell your debt to persons who have alternative methods of collecting payment. Please believe me when I say this is not a threat it's a promise". He has included a copy of the loan agreement. I am absolutely terrified - it sounds like he is going to send some scary people to our door or do who knows what to us? I'm already trying to get over PND after having a very premature baby and I can't cope with this. I'm not sure if I have posted in the right section but I feel so stressed out and panicky today I'm in on my own and really scared.
