Still no joy from Momentum

I joined Momentum under the impression that I would receive cash back on my insurance premium based on my driving behaviour. Now it seems I have to download all kinds of apps, jump through multiple hoops and keep myself busy with admin all week in order to comply. I have received no feedback on logging in and registering for the apps despite multiple queries. I have also been told that my phone has the ability to tell Momentum if I brake too hard and suddenly and this is how they will judge my performance. Really?! My phone can do that? This all seems like a big fat **** where they let you think you are in charge of getting cashback when really it is up to their discretion. Seems very convenient.
