Cell C shocking service

Cell C doesn't even deserve a single star. I have a Cellphone contract with Cell C (including Insurance) going now for my next upgrade already. i have been Dealing with Cell C Oakfields, i handed in my device for repairs on 30 / 10 On Monday 10 / 11 i went to the store to enquire about my repair, only to find out that the documentation (claim forms have still not been submitted) I followed up on 15 / 11, spoke to Garth (at customer service centre) & up till now still not all documents have been received by them. But i have a quote of R4 539 for a new screen, yet i pay insurance every month, yet i'm paying for a screen repair.

I'm at my wits end as this is not the first time i'm experiencing such poor service from Cell C...

Here's my reference numbers just incase someone from cell c see's this and decides to do something to help a Paying Customer, who now is sitting without a Phone, due to slack service delivery. 2021 / 06 / 29 - GPJOH410658 - This cellphone (also for a broken screen) also had insurance on the device, got dropped off & 3 weeks later got a price of R4 800 to repair screen, told them i have insurance, again 2 weeks later still got no help, so i asked them to return my device, i will get it repaired at my own cost. 2022 / 10 / 30 - GPJOH452389 - Sent in this device for screen repair, under insurance, until now the don't even have the correct documentation from the store.

After i went to the store and spoke to the manager ( Cedric ) who keeps asking me a question & when i answer keeps telling me "Listen to me"... It was so frustrating to speak to this guy. Then eventually i got the number for Oakfields Cell C Area Manager Millicent - Who also makes promises to sort this mess out for me, after going to the store. I was supposed to meet Millicent at the store on Monday 14 / 11... On Tuesday 15 / 11 when i called her to ask what happed with our appointment - She says "Oh sorry i am booked off!" So meaning i must still wait for Cell C to one day catch a wake up... I asked for the Regional Manager ( manager for Millicent) Niven Naidoo - Who doesn't even answer my calls.

WHAT AM I TO DO - CAN ANYONE OFFER ME ADVICE..?
