Oi Assistance

Hi NANOG, I'm hoping someone out there has had some experience with Oi Telecommunications. We've been struggling to work with them to get a couple of circuits in Sao Paulo live. The primary problem is mostly a language barrier. Is anyone aware of an English speaking NOC email address or phone number for Oi? After months of back and forth through a third party translator working with our account team, I've reached my limit and am hoping there's another option to get some technical assistance with the BGP configuration of these two circuits. Any advice will be appreciated. Thanks, Brian
