There is great importance on Rosh Hashanah of avoiding cults. Even if they entice by pretending to keep mitzvot, once they worship human beings, the mitzvot do not count. That is what you find in the Gemara about a shofar of idolatry. מכתת שיעוריה. It is considered to be ground up so one does not fulfill the mtzvah of hearing a shofar from it.
The best idea is to go to a place of genuine Torah like a Litvak yeshiva.
[While it is true than some Litvak yeshivas and kollels are run in a way that is less than desirable, still there is a difference between the surface and the substratum. If the substratum is a spirit of authentic straight Torah that should be enough to outweigh the surface problems. That is in any case what I discovered in Shar Yashuv in Far Rockaway and the Mir in NY,--that the substratum was that of authentic Torah.]
[You would normally hope Sefardi synagogues would be immune to this problem but I have seen than that is not the case. The Sitra Achra has penetrated there too ]
