Frustrated customer

I recently bought a new device from cell c. On the day that my device was recieved I was advised by the call center agent that i would need to call *** to apply for device insurance. From 19 February I have called them 15 times, been to a store twice, called the store 3 times, emailed the store and emailed the device insurance 4 times. Eventually on 02 March they sent me the sms to confirm that I accept the terms and conditions to which I did immediately. I then called an hour later as requested to confirm if the application was successful and the lady told me that I would recieve an email within 48 hours confirming the application. I then called back again on 03 March and after minutes of waiting I got through to an agent who pit me on hold for 7 minutes and then cut the call. I had to call back in and another agent assisted me and advised that they will resend me the sms confirmation. I waited for a few more hours and called back and she advised that she was still waiting for the guy that generates the sms as he is busy srking on it. It is now 24 hours later and I am still waiting for it and my device is still uninsured!!!
