I would give 0 ratings. Pathetic service given by Grey Quest. None of the what's app service or email service team have been responding from last 3 months. Customer support senior Tanvir does not have understanding. It's like speaking with Robot. Unfortunately I need to bring RBI in picture to take up the matter against Greyquest.
I will request all school and parents not to give any opportunity to them and enroll for payment option. There are better partner available.
