No service delivery

I have recieved my Sim card on Monday 05/09/2022. I recieved an email to say that it has been activated. Since then i have come into contact with customer service multiple times a day. The problem is stil not resolved. The agents keep escilating the problem to the billing department but nothing further happens. This i really poor service.

I have used alot of money on airtime calls, i have payed my monthly installment and do not have the joy of using the data Sim.
