Payment made online not credited to my account

[Brizoh71]

Due to a bank issue my last direct debit bounced. I paid the outstanding balance within 24 hours of realising and before it showed as overdue in My O2. 

Having just logged into My O2 this evening my account shows as overdue despite me making this payment which effectively put me in credit. How then can my bill be overdue? I'm not paying it again and have my 'credit' applied to my next bill.

@Brizoh71 How long has it been since you paid the outstanding balance? It can take 48 hours to clear O2's account. Best thing for you to do is speak to the Payment Management Team on 0800 902 0217.

The opening times are:

Monday to Friday – 8am to 8pm

Saturday – 8am to 6pm
Sunday – 9am to 6pm

Still showing overdue this morning, looked a little deeper and it appears the payment has been allocated to another account I have with o2 and not the one the payment should have applied to.

Accounting systems are a mess at the moment due to a botched upgrade by O2
