Caller: Indian accented, very pushy woman from an IT company

They rang me a month ago and I said to call back. In the meantime, I researched them and found a pile of complaints. They look through web domains that are parked, then call the owner and push to create a domain to sell your products. When I tried to say I'd researched them and they came up as dodgy, she got all defensive. Was so pushy and talked over the me the whole time. (Not sure that's the best way to get a customer?!)
I hung up and blocked the number.
