Ola Cabs / Ani Technologies — Spam calls and data sharing

I've been receiving spam robotic calls marked from Ola and it has been interrupting my day and my work. It starts from 8 am and ends at 12 am. It has been really frustrating and each number I keep blocking but I get calls from different numbers every time.

Please stop sharing our data with third party. This is equivalent to you guys sharing it with China. Kindly get this trouble off me or I might stop using the app. Not that it would matter losing one user but it really is annoying.
