for you to register or subscribe to amything with email or phone , you need to confirm that those account belongs to you.

Verification email or sms code would be sent to verify.

Question to you is how they manage to confirm verification of your account?

- Compromised phone?
- Sim jacked?
- Compromised email account?

If you're a victim of Identity theft, better make police report and go to banks to verify whether anything has been tagged under your name. Better check CCRIS CTOS  also..

go to bank and complain to deregister the email.
how the guy got your email in the first place is a question.
if lucky, he just register. if unlucky, he got access also

If Gmail, do you have “.” between your address? It is likely because of this where someone registered similar address with or without the “.”

I have a feeling the bank was doing some data migration and cleansing.
Then somehow tour email got matched with another guy same name.

Another reason might be email validation was skipped during profile update processes

If you check the recipient of the email, was it to your email with . or was it to another slightly different variation of your email (. in a different location or no . completely)?

I’ve faced similar with someone using a non . variant of my email address and I’ve been getting Lazada invoice for purchases the other person made 😅

I think wrongly added.

I too received such emails. All because of Gmail.

For example.

My email is ABC.123@gmail.com

But that idiot used ABC123@gmail.com instead.

According to Gmail, ABC123@gmail.com is same as ABC.123@gmail.com too.

Yes, I've done that before when someone uses my email address. Manage to take over his Facebook and Instagram. But for banking definitely cannot, need to verify mobile number.
That idiot even uses my email to register Apple ID, but luckily Apple quite strict otherwise I would have reset and locked his iPhone.

Call Astro using the info in the bill, request to subscribe the most expensive package or request termination.

Which bank is this? Sotong? Tiger?
