Device plan Payment overdue

[Nicole13]

I have had an overdue payment message. However my plan since paying last month has said that I am due to pay £0:00 left of my device plan as I have paid up my amount. 
I am confused as to why this is now considered overdue…am I supposed to pay over what is due when it says £0:00 left to pay? 
please could someone assist as I don’t want to be in arrears. Thank you

This looks like something you’d need to call O2’s customer service team about – give them a call on 202 or 0344 809 0202

(or the specific Payment management number 0800 902 0217 )
