It started happening to me when I registered a domain name and made my phone number available via whois lookup. The same day I got an Indian company offering me web services for the new domain. Then it escalated and every dodgy Indian web company started calling me. I managed to change the details and update the phone number to a local law enforcement agency's number, but I guess the number was online for long enough to spread through some kind of Indian scammer network. I started getting calls offering me to remortgage my home even if I don't have a mortgage, pretend calls from the taxation office (in American accent even though I'm not in the US) and a million other things like SEO services etc. A lot of the times they'll route calls through a local VOIP number and even have a local mobile number popup in my screen. They could totally scam me if it wasn't for the Indian accent that gives it away.
