I have received an email on a couple of occasions supposedly about issues with paying my account, the sender's address is as follows:
TPG - Telecom <email@example.com>
Of course I have deleted them, but in the meantime we all have to be aware of these scammers trying to con users into giving out their payment details.
Thank you for taking the time to raise awareness on these phishing emails. We suggest that these messages be tagged as spam as well. This will enable our system to filter and tag these as junk the next time a message is delivered using the same email address.
