Faulty Discovery Drive App and no response from Discovery

I wrote a review on the 26th of August about a Discovery Drive app error, detecting movement where I was parked. Discovery rep**** immediately, saying that they would look into it. Nothing since, even though I have been soliciting a reply and asking for feedback. I also tried the Whatsapp chat but was told they are unable to help. Not sure if it is worth staying with Discovery Insure, considering that their reward system is based on a faulty app.
