Need help contacting "Hewes"

[invisiduck]

I wondered if someone on here might be able to get in contact with "Hewes". He sent me a deposit by cheque a while ago for an ATN Night Vision Monocular which went through fine, then i got a cheque for the rest of the payment, but i went to put it in the bank and found it wasnt signed. Ive left 2-3 messages for him to let him know but no response, i dont want him to think ive dissapeared, if someone who knows him could please tell him about the situation, i would be very greatful.
