Had seen a lot of threads here at DP claiming XM doesn't pay and doesn't reply to emails. Infact I had participated in the same threads. But today i contacted their customer support executive C.Haley and she helped me to get the Payment. Users can contact her and get sorted out of the issues...whatsoever it could be. She is very cordial & nice ... Find my payment proof attached.
Why dont you read their FAQ ? "Publishers are paid on Net 35 days from the end of the month in which ads ran."
Got my first payment with them. Since we made over $500 we had to get wire transfer but everything went smooth as butter and this wasn't even a full month of revenue.
