Can't topup using debit card or voucher July, 2022

[MOALI]

First time O2 customer with pay as you go sim and can not seems to be able to topup. 

I have been trying from one week to try and topup. 

When trying online through MyO2 using the debit card I get error stating:

'Sorry, it’s not been possible to take your payment. Your phone has not been topped up. Please try again or use another card. If the problem continues you’ll need to contact your bank.'

Purchased a £10 pound voucher from shop and when trying over the phone to topup a recorded voice message comes up that there is a problem with voucher topup system. 

Can not find any phone number to call O2 and can not find a way to topup the sim.... 

Any suggestions....

Check out this guide which shows various ways to top up Guide How to Top Up (PAYG) 

If you are still having problems then contact O2.

Give O2 a call on 4445  or 0344 809 0222.

Or you can message O2 on Facebook ( https://o2uk.co/O2CFB) , Twitter ( https://o2uk.co/O2CTW) or Instagram ( https://o2uk.co/O2CIG), hopefully they should be able to help.
