Please I need your help guys

hello everyone, i got a problem with COD offers in adcombo, I have a website I have really very good traffic, I daily get 1or 2 order for the product but always they go in reject, even on my prelander I write that the customer should answer to the call to confirm order,so everything is clear, my traffic is 100% legit,I ask my AM to give me script call of these all rejected but she keep say that she request call center.i sure these reject should convert to a sale. I need your help guys what should I do? Sadly this network seem that they give all their attention to shitty advertisers not for hard working publishers,I will appreciate any suggestions from you guys and sorry for my English

Oh you're getting the same issue in April
