I also had my appointment on May 31, 2017 for renewal and in December I still had no answer ... Opt for the extension and pay it on December 11 and on the 17th of the same month I had already arrived at the consulate and I have stamped the extension in my passport 📍
The same thing happens to me as incompetence and nobody answers the phone. Also the schedules are inaccessible until 1pm.
