221g case not updated almost two months

Hi ,
I attended my first H1B Stamping in Hyderabad Consulate on April 26th. The VO gave me 221g white slip and asked me to send the petition documents through email. I sent them on May3rd . From then my case is not getting updated on the CEAC site.
Could you please let me know whom we should contact? As its almost 2 months now

There is no easy answer to this. There is no SLA and no good way to track. You have to rely on online tracking through CEAC site and this could take days, weeks or months.
