This business is awful, they pretend to do the work, they pretend it works and then you find out it doesn’t. Then they say they will fix it but all they do is add weeks and weeks of doing very little. 2 months past the timeline, 10k out of pocket and nothing decent to show for it. In over 25 years of handling commercial relationships, this is by far the worst experience I have ever had. I came to tears on a number of occasions. Absolutely useless. 0/10.

This company has been marketing using spam for a number of years. They send millions of spam messages by email using burner email accounts, and not identifying the company they come from. Only when you pretend to be interested do they then follow up from Blocktech Brew directly.
I have positive proof of this, by replying with a name which I never use elsewhere. The resulting email from Blocktech Brew contains this name.
A company which uses spam for marketing:
1 Is unclear about legal and data protection issues, and therefore not a good idea to use for your project, or
2 Desperate enough for business that they are willing to break the law/rules of ethical practice in marketing.
On this basis, I would discourage anyone from using this company, as they are encouraging spam and given legitimate Indian businesses a bad name.
