Does O2 payg use Mi-pay.com - possible scam

[effsweet]

Hi guys,

I've had an email from  

O2topup@mi-pay.com

telling me my top=up was successful  -   as   my payg balance has not changed in the 4 days since the message 

I think this is a scam of some sort.

How can I remove my credit card details from myO2 & Register a new one?

Is this what I need to do?

Has anyone had this happen to them.

TIA for all reads & replies

Thanks:   F

@effsweet  On googling Mi-Pay, it certainly isn't for you at all. All ways to top up here Guide How to Top Up (PAYG)  You can also change your payment card details in My O2.
