not paying dues

Hello to all,

I have unlocked rogers imei over the past few months. He used to pay as his imeis were done and recently has started holding my money. Now i have requested him to pay his balance of $ 1378.49 and he is refusing to pay.

He sent some imeis that were not rogers and clearly on my website it is stated no refund for wrong carrier when it comes to rogers, he argues all source refund, however i am not all and my source doesn’t refund me he charges me.

He owes me about $ 1000 from credit used on my website and $ 37X.00 he sent some imeis by email.
