Is this Prepaid? It's not something new but how do u get this number u r using at the first place? Need more info to help you bro ✌(-‿-)✌
I saw you posted in another thread. I guess you don't have the SIMPack anymore? Do you remember registering the Prepaid?
In this case, lets try if Celcom can help you. It's just commonsense. If what you are telling is true, you can just walk in to any Blue Cube, tell them the story, if you can even tell them where you registered the prepaid, it would be good. Give 3-5 frequent numbers that you called. If all these matched Celcom's database, logically they have to 'fix' the ownership data.
The question is, if you are the one registered the line yourself, how it can be somebody else's name?
All the best!
