Angry customer

I have been a loyal customer to Cell c for the past 5 year, I have a cellohone contract with cell c n insurance. I have never missed any installment nor any late payments. I lost my cellphone in February 2023 I have reported my cellphone lost although till today I haven't received any replacement of my lost cellphone and yet cell C is still not failing to debit on my account, to make things worst for me they have deactivated my number without informing me. It's been 5 months now and my claim is still pending. No communication or whatsoever from cell C I have been sending emails and still nothing happens seems like I'm communicating to myself. I'm so disappointed and very angry I don't know what next to do all I know is I need a cellphone😡😡😡😡😡😡😡😡😡
