What’s number can I reach o2 on

[pip5]

I’ve received letters saying my numbers have been stopped due to owed money although the direct debit had been coming out on the same dates every month this letter was sent 5 days before the next bill was paid?

You need to contact O2.
All numbers are in this guide Guide: Coronavirus Community Help and Support 
When you call, you will be asked for the reason you are calling.
Stay silent for 15 seconds and you will be taken to the keypad options.
Press 2 for Everything Else
Press 5 for More Options
Press 7 for Anything Else which will put you though to someone.
You can also try saying "Upgrade" or "Fraud" to be connected to an advisor.
8.00am is the best time to call if you can.
