Caller: Indian Scammers (NBN Co Scam)

This caller claimed to be from NBN Co, regarding unstable internet connection. Please understand unless you have contacted NBN Co for the 'overbuild' program they will not contact you directly, your service provider will call you

I have received calls from these two numbers recently.
Don't know who they are. No message left. Have to assume they are a pest/scammer. From the same call center perhaps.
