How do I pay an outstanding balance after i've changed network?

[Jonny95]

I was an o2 customer, but changed networks 2 weeks ago and transferred my o2 number over.

I accidentely cancelled the direct debit before my last o2 bill had been paid.

I've received a text from o2 stating that if the bill isn't paid for soon, they will add a late payment charge.

They provided me with 3 ways of paying the outstanding bill:

2729 - I called but the number wasn't recognised

0800 588 4217 - I called this automated line and pressed a few numbers to get to the section I needed, but then it said it can't help me

My o2 account - When I log in it says "You don't have any products or services in this My O2 account."

Additionally, i tried calling the "thinking of leaving us" department, but was on hold for over 10 minutes before I gave up.

I only have 2 days left before a late payment charge is added, so any help or advice would be greatly appreciated. Cheers.

@Jonny95 

All ways to pay here Guide: How to Pay Your Bill (Airtime & Device Plans) 

All numbers to call on here Guide: Coronavirus Community Help and Support 

and you're gonna need to hold for longer that 10 mins these days.

Call at 8.00am to avoid long queues.
