Same thing. Keeps ringing but hangs up after 30 secs

Told me because I have always paid my Telstra account on time she was going to offer me a special deal. I said I never pay my account on time so the must be lying to me and then she hung up. I'm not even a Telstra customer, she is playing they laws of averages. If she rings enough mobiles she will land on a Telstra customer.

2 calls from this number, 4 hours apart. Tried to call back, number not connected.

Its Dodo, they have used this number to sell agreements to me.

Called asking for my current mobile plan, and tried to offer me a better deal for the same price. Goes by the name 'Superphone' apparently leading service provider for Optus, Telstra and Vodafone. Dodgy af

Received a call when I picked up it started to ring on other end. I just hung up

keeps ringing at least once a bay hangs up when answered going on past ten days. Phone turned off when returning calls.
