Hi I want to know a number under what name it is registered

I Doubt customer support are gonna give out another customers information,
But how can you tell if it's a number that's in service from Fizz?

Well, it will be hard to know that.

There is a person trying to contact me again n again i figured out it’s the the number from fizz can you give me the registered name

Welcome on Forum. It's a private information. Then it's protected. If you just have information from the prime section it's hard to go further. If the info there looks like a username you see on the forum you can try to check with that fizzer if he is the one you are looking for. For that, use the little enveloppe next to your icone to write a message to this Fizzer (clik on it and after click on the little square with a pen then write his username in the recipients line). If it's the good one he will see if he wants to share informations with you.

This is private information, no one would ever give out that kind of information.

Just call the number.

The phone number you are receiving the calls from, could also be spoofed one.
