If you want assistance from the Community Forum then you'll need to provide a bit more information and context than that and to explain/describe your question/issue clearly and in detail.
What exactly do you mean by "credit gone" and "I need to renew and pay credit"?
What exactly are you trying to do, what steps are you taking to do it, and what issue are you having in trying to do it?
You might want to read this key post about plans and payments in case it helps at all.
If you need to contact 48 support about this then see the links in my signature below.
