Cell C& Cell C insurance. (Shocking service)

I am on a contract basis with Cell C - I have been for about 3years now. I changed over from Vodacom to cell c which is seriously the biggest mistake i have ever made and have had nothing but extremely poor service with them ever since. After getting an iphone 6 via cell c i upgraded over the phone about a year and a half later, with a consultant to my iphone 7 in which the contract phone was then couriered to me. I then took out cell c insurance a few months later and about 5-6 months after that my cell phone was ******. I have attempted to claim back from C insurance with various issues!

1.) They have the WRONG IME number for me on their system so they can not issue my new cell phone as they say my sim card was never registered with that IME number, the cell c contract department issues me with the correct IME number and so does their cell c store but for some reason someone entered the WRONG IME number when insuring my cell phone. 2.) I have been transferred from department to department to rectify this but because the quality of service is so bad i don't ever seem to speak to someone who can help. Including the insurance department themselves. 3.) I got told that the cell store needs to screen much their screen with the correct IME number as they don't believe the IME number i have is correct. - Unfortunately i don't still have the box otherwise i would take a screen cap of that. 4.) after being told they need to do that they then need to send it through to them, they will issue us a ticket number and after which i must follow up with that ticket. Lets not fail to mention with cell c insurance you only get your cell phone in 21 WORKING DAYS. 5.) The lady at the cell c store was kind enough to follow up for me only to be told the cell phone that is actually insured is a iphone 6! i have never insured the iphone 6 i once had and even have a congratulatory letter from cell c saying my iphone 7 128 mg is now insured.

Unnecessary and disappointing. Needless to say i will be moving far away from Cell C.
