Incorrect ID number

I signed up for discovery insure on my vehicle from the 1st of November. From day one it seems they have add the wrong ID number to my profile. The last 2 digits of my ID number is incorrect on my policy but it doesn't get resolved. After now 2 months nothing has changed. I have logged emails and calls so many times and the same reply keeps being sent back that "it has been escalated to the highest level and will be fixed in 2-8 hours" or that "it will be fixed with 48 hours. For two months now I can not access my account on the insure app and I haven't received any drive points on my vitality drive rewards on the discovery app. This is unacceptable and very poor service.
