Nobroker — Nonstop Spam emails even after account termination

Created an account to browse through options and immediately regretted it.
The number of calls per day reached 15!!!
Finally managed to block calls and SMSs, however emails, that kept coming nonstop.
3 years later, I'm still receiving spam emails.
Using a data deletion site, I requested my account data be deleted and to stop sending spam emails.
Although initially they complied and gave me a confirmation that the account has been terminated, immediately the next day onwards I kept receiving spam emails again 1 per day.
I have never faced such direct relentless harassment. For this to happen, to not just one customer, but to many, it suggests that the management has deliberately decided to resort to harassing customers to make money and then decided to train their systems and employees on how to do that specifically.
If that is not "unfair trade practices " I don't know what is.
The message is clear, they'll do anything and everything to make money regardless of consequences.
This is a clear sign that these people are morally bankrupt.
