Your post was blank @MelissaD1005 and there's not much to go on in the subject line alone.
If you want assistance from the Community Forum then you need to explain/describe your issue clearly and in detail and provide some background information.
E.g. what exactly do you mean by "topped up"?
What did you purchase?
Membership plan, add-on, cash credit?
What does your Transactions page say about your recent payment?
Do you have a currently active membership plan listed on your My48 account dashboard?
When was everything working ok for you last?
What exactly do you mean by "nothing is working"?
What exactly is/isn't working for you now?
Connection to the 48 network - i.e. signal bars?
Incoming/outgoing calls?
Incoming/outgoing texts?
Mobile data?
What happens when you try to use any outgoing services?
Any error messages?
If you need to contact 48 support about this then see the links in my signature below.
