Anybody here with performics .. they owe me over $5000 and they take forever to pay .. its four months now and they have been sending me checks every two to three weeks of $100 to $200 ... PATHETIC ! their merchants dont pay on time ..
Is the earnings from one merchant or multiple? That would help you figure out if its the network or a merchant(s).
Contact them. More importantly if you have to contact the advertisers. I had over 20K in PC Connection/MacConnection and Circuit City tied up for 60 days before I went off the deep end and told them to get with the program. It took a lot of exchanging but I finally pointed out that I was sending a lot of business their way from just two sites and that I would dump them in a heartbeat if they didn't start coughing up the dollars. It may take a bit. At least send one email a day. Or you could try disabling what your currently running and letting them know you will not enable it until you have been paid.
During my 4 years of marketing i came to a conclusion that adsense and cj is the best when it comes to paying on time ... sometimes your better off making less and getting paid on time .
