Stay away from Absa activate

Yesterday I took out a Activate policy with a broker who assured me that I would get a discount. She also said that I can manage the policy via the activate app. Firstly, the app doesn't work. It opens for about half a second then closes again. Useless. Then I looked on my banking app and the p[olicy is there and it reflects the premium before the discount they promised. The consultant did not take my car details correctly after numerous questions and back and forth she still got the car details wrong. The policy is already invalid. I want to cancel this policy before it kicks in on the 1st September.

Unfortunately there is no other way. I want to cancel this policy ASAP. I also read alot of bad reviews about the app. Many people struggling to open the app and saying to stay away. I've sent an email and have not heard from a consultant as yet
