Good Day

I had a small bumper bashing with another vehicle about 10 days ago.   Both cars incurred minor damage.  I believe he was at fault and he believes I was at fault.

I am insured but the other driver is not.

After the accident,  I asked the other driver to wait so that I could get his details,   and then he asked me if I knew of any repairers.   I pointed out the one I knew was closest.    He then sent me the quote.   I pointed out to him,  that it is not really my responsibility as he was at fault,  and he is now saying that because I asked him to wait,  and also because I told him where to go for a quote,   that meant I was taking responsibility for the whole thing.

He has now gotten someone else involved,  and she keeps messaging me asking me for my insurers details,  and the case number so that they can claim against my insurance,   but I don't believe that is fair since it was not my fault.   This person keeps messaging me,  and I now asked her to correspond via e-mail only and to please stop sending me messages.

I am being told he cannot work now and cannot pay rent because he earns his living through his vehicle which cannot drive till it is repaired,  and I feel bad for him but also really think it is not my responsibility.       If he is a driver (private or for a company) surely he as a responsibility to have insurance?

What is the best way to handle this matter?
