Recharge

I recharge 1gig on my simca Rd but didn't connect, take it to Zevenwacht mall cell c. 1st said modem expired but simcard is active, but the problem was a simcard. They said I must do sim swop and I must do affidavit I did. Today they said the number is not registered my name. Question is why I managed to recharge if the simcard is not mine? They confirm 1gig on the number they can't do anything. All in all I'm losing my 150 like that after being driving up and down. No one is registered under that number and my simcard they said it doesn't have a number. When he checked the number on the simcard is registered under my name. But go out of cell c unhappy because I'm losing my data whereas I have all the proof that is mine. Please advise I feel being ******. Because how can I recharge successfully if the simcard don't have a number?
