If you want assistance from the Community Forum then you really need to provide a bit more information than that.
What exactly is the issue that you're having?
What happens when you try to use mobile data or make a call?
Any error messages?
Are your APN settings configured correctly for mobile data to work properly?
Can you receive calls, send/receive texts?
When was everything working ok last?
What exactly do you mean by "top up"?
Membership plan, add-on, cash credit?
What does your Transactions page say about your recent payment?
Does your My48 account dashboard list an active membership plan?
If you need to contact 48 support about this then see the links in my signature below.
