Repair Service & Device Insurance- Dismal and appalling

I've handed my device in for repair at Cell C, underwritten by #Hollardinsurance. Recieved a message on Friday that my device has been asessed for repair, and that I need to call customer care to confirm my quote. I have called several times since then. Each time I am transferred to repairs the call drops. The Call Centre agents are unable to assist and keep repeating the same party line each time I call. So effectively I've been paying device insurance for nearly 3 years for nothing. I will be taking my business elsewhere when I my contract is completed.
