And I pay them as I was saving the slip after pay. I have a prove. My last payment it was on the 07 August 2025 and the said I pay for everything. Cause they were suspend my number not working anymore. I call them on the second day to reactivate my number,and they said I must call on the 22 August 2025 to check if is reactivated. I did call them and they said I'm owing them again cause they put more airtime on my SIM card but when I'm trying to cancel this contract they don't want they just do back and forth I don't know why cause I'm not working anymore and the phone it was an gift for my son. I don't see any reason to continue with the contract.even though I try to cancel it I told them to cancel cause it was gift.guys I need a help cause the lady I was talking to on she was busy telling me that I must pay until November and which is my contract ended last year on June. And they threaten me to blacklist me if I don't want to continue with them.
