Virgin emailed me saying this Hi, you've reached your agreed credit limit. Your service will be temporarily restricted. Please immediately make a payment over the web or by phone on 1300 555 100.
I am on a $40 post paid plan + $5 for extra bandwidth. I don't have a credit limit and am nowhere near my allowable bandwidth usage. Even if I do go over, I get billed - not cut off! I have moved to a new house in a mobile black hole so Virgin agreed to cancel my account but that won't happen until they send me a satchel to return the handset by courier. I was told it will be 5-7 working days before the satchel arrives. I'm only one day into that. In the meantime, I have arranged a service with another provider but the number isn't porting over from Virgin. This is either quite a coincidence or there's some relation between this 'credit limit' message which makes no sense at all and the hold-up with Virgin getting the service to my new service provider. I just can't go on not being able to be contacted while I'm at home. My elderly mother has major health issues and I'm the medical power of attorney and she, her doctors and the hospital can't get in touch with me. I'd planned to go back to Virgin when we move on from this location next year but now I'm thinking twice.
All post paid mobile customers have a credit limit, you can learn more about these here.
It sounds like you have since ported your service to another provider, when this happens that credit limit e-mail is automatically triggered and can generally be ignored, it just means your account has closed but you have/will have an outstanding balance for your final usage with the service when billed. If you still don't have service with your new provider we would suggest contacting them.
