First off it's not really a good idea to post personal details such as your name and phone number on a public forum like this where anyone can see and use those details.
You might want to edit your post to remove them.
Your post is a bit confusing and the nature of your problem isn't really clear.
What exactly do you mean by "data credit"?
What exactly are you trying to buy?
Membership plan, data add-on, cash credit?
What happens when you try?
Any error messages?
What exactly do you mean by "my number has been disconnected"?
What are the exact symptoms of the issue?
When did you last buy a membership plan?
What do you mean by "recovery" and "please help me recover my number"?
