Caller: Definitely not Telstra

I assume a tech support scam posing as Telstra. They call me upwards of 5 times a day and never answer the phone when I pick up. If I don't pick up they spoof another number and try again. Whenever this kind of sh*t happens you can bet it's a New Dehli tech support scam call. They harass and harass you to the point of insanity hoping you call back. I've tried appealing to their common sense IE they know I know it's a scam so why waste money calling yet they don't stop. Why? Because they think this tactic will achieve profit. If they answer tell them to get f*cked and change your number. They will NOT stop.
