You were too late with no way for me to check in my logs what really happened with your rental and provided no evidence error was on my side.
So either you are too incompetent to configure and rent a rig (not my problem) or trying to scam me because you heard I am very helpful in resolving these situations in favor of my renters (your "friend" can tell you that). Now think what you want but I think you(2) tried to scam me and I got you, so matter is concluded for me.
Most pools keep logs for weeks so I find it very hard to believe that you had no logs after 4 days. Even if that was the case you would have been able to easily tell that your rigs were mining on your backup pools as you can check your wallet for how much BTC was coming from your pool.
I did have the rig configured correctly, and I did provide you ample proof that I did not receive any mining to my worker.
My friend has informed me that your backup pool is ghash and I know for a fact that Ghash will provide a daily hashrate for the past 30 days, right now it will go back as far as March 29 2014.
Bottom line is that you were given payment for a service that you did not provide. I don't know what country you live in but where I am from that is stealing.
