I had an Indian accented man call me to tell me he needed to fix my router to avoid total loss of internet access.
Me: Who did you say was calling?
"I am Manish from BT OpenSearch, sir."
OpenSearch?!
"Yes, sir, BT OpenSearch."
Dude, you're trying to scam me and can't even get the name of the company right!
"I'm from BT OpenSearch."
Look, even if you got the name right you wouldn't have anything to do with equipment beyond the wall socket in the customer's house. Goodbye.
Honestly, the calibre of scammer is really going downhill.
