phone won't make outgoing calls

[HP1]

I went over my monthly limit (thought I was making an international call via wifi but apparently not). I paid the overdue amount on Saturday - shown on my account - but my phone still won't make outgoing calls or pick up data (today is Monday).

You need to speak to Payment Management from another phone on 0800 902 0217 and they can help
