BLOCKED EMAIL - HELP!

I am unable to receive emails from a specific domain in the UK. Over a two week period, I have made at least 6 calls to the support desk and sent several emails, and each time i am told that it has been resolved, but i am still not receiving emails from BITFINE.BIZ. I have also emailed the ATT abuse address at abuse_rbl@abuse-att.net. 

Please help me to reach a resolution or explain to me why it cannot be resolved. The company is not an abuser, simply someone i need to communicate with.

Thanks,

William
