Does anyone know if this number is a scam?

Caller: NBN company

the caller called my work landline and wanted to test my internet speed because they had a report from the NBN that my internet was slow. I don't have the NBN, unsure if this is a legitamate service. I hung up he took too long to get to the point.

Caller: PayPal

Saying my ID had been used in a scam for Paypal for $1100.00. Wanted me to down load an App to save my account.

My Google Pixel phone warned it is a spam number, so I declined it.

Caller: (03) 9093 8098

Call back scam

I would say this is definitely a scam. Tried to tell me I had charges to my eBay account. I don't have an eBay account. As soon as I started asking how they had my information they just kept repeating the same line over and over. When I accused them of being a scam they hung up on me.

Caller: scammer - "from Paypal security department"

This is a scam call. I ended the call as soon as the individual made his false claim of being from PayPal. This is a scammer - avoid.

Caller: Amazon

Highly likely to be scam

I think so. They called and asked if I was speaking by name, then hung up. I called back and the number could not be connected. Suspicious.

Caller: No idea - They said 'Amazon'

They said they were from Amazon. They said we have a charge for you for from overseas on your amazon account for a iPhone. I hung up, but pretty sure it's a scamT.
