3 vpn and 2 proxies?! You will be lucky to send or receive a single bit. Its very slow for me when I have just 2 vpn and 1 proxy, I can't imagine what it would be like to have 3 VPNs and 2 proxies.
Have you tested the speed? You know Payment Processors use your speed as one of the factors that goes into their risk assessment. If its too slow for the location and/ or ISP then it becomes suspicious and payment won't go through. But even saying that is pointless when I doubt you can load a small html page with 3 VPNs and 2 proxies.
