extremely irrated

I had a Cell C contract for a very long time, I never experience any problems until now, I upgraded my contract in June 2021,long before my Samsung A10 with insurance expired, got the Samsung A02 phone for 5 months, the Samsung A10 expired in November 2021. The upgraded Samsung A02 LCD was damage in December, when I called Cell C that is where I was notified that the Samsung A02 do not have insurance, no one explained that I had to call to move the insurance to the new upgraded phone all they can say is SORRY, sorry doesnt help, im paying now for a contract which I dont have a phone, I have to pay to repair phone,that is the same amount as the worth of the phone. When I called to find out if the insurnace is still on the Samsung A10 they said yes, cause that phone was stollen, I have to pay an excess amount of R250 which I paid into Cell C account. Im extremely irrated. No device but paying........ Im battling with Cell C, I called them since November 2021..........
