There is some reports that they sell your contact information to shady investment marketing companies. Many people have observed a sudden influx of calls from small, unheard of investment companies calling them up with investment offers, after they have signed up with Zerodha.

Also there have been much publcised issues with futures trading on their platform, with a court ordering them to refund a large sum to an invester.

There also have been issues with outages:

"Unfortunately, the steep increase in client base and consequent surge in orders has led to several bottlenecks because Zerodha’s infrastructure has not kept pace.

The system conks off often and it is common to find traders expressing their angst against Zerodha, especially on days of high volatility.

Yesterday was a textbook example of this.

The news about hostilities between India and Pakistan led to a sudden surge in volatility.

Traders scrambled to take new positions or cover their existing ones.

However, Kite, Zerodha’s flagship trading system, was down and out.

It stopped taking orders, which is an unthinkable eventuality given the mayhem that was being witnessed in the markets at that time."

I've talked about the technical issues in a couple other responses on this post.

About spam, we've been working with the capital markets regulators, cyber crime units (Police), and TRAI (telecom regulator). It is a nasty issue that plagues all capital markets institutions in India. I'd gone into some detail on the data leaks on this Reddit AMA last year: https://www.reddit.com/r/IndiaInvestments/comments/bhv18e/we...

Ah..Ok, so contact information may have been leaked at various stages of the regulatory process or even at the Telco..

Good that you are taking action on the spam callers and hopefully other improvements have reduced the service interruptions. The regulatory environment possibily does not look with kind eyes on new entrants in the financial services industry. So I think you might have had many struggles to reach where you are.

I really didn't intend to shower negative sentiment about the service, only to highlight a few complaints I have heard, but later I saw it had become the topmost comment.

Wow, fascinating. You're being screwed by your service providers. Great job tracking that down.

In addition to a do-not-disturb list, can we have a nationally curated list of scamsters and aggressive ngos? The blacklist on my phone is now nearly 25 long.

As an analogy, it is precisely this kind of a distributed tracking and control of spam and DDOS that made cloudflare a valuable service.

That's just awful.These deep rooted issues plague so many good movements around our country.

Agree with the contact sharing thing. As soon as I registered I started getting telemarketing calls from many "Investment Research" companies giving me "recommendations".

This might be only a single anecdotal data point, but I have been using Zerodha for more than a year and I have not received any spam call from any such investment companies. So whatever the spam call issue maybe, I doubt it is Zerodha selling your data.

I signed up couple of months ago and received no such calls.
