Hi, I recently received a bill from Telstra billing me at 28c, I know it's not much but if I pay this they might bill me with a higher figure, I don't think the letter is real but what should I do?
I'd be very careful of the emails origin. If you don't have a Telstra account send it to junk. If you're really concern I suggest you speak to a Telstra rep 132200.
Sounds like a phishing email. Any links included to make the payment?
Alternatively its some Telstra computer burp.
Either way as @caaf says, contact Telstra directly (not aon any links provided in the email) and ask whats what.
