Nedbank insurance not putting customers first

I have building insurance with Nedbank which covers gate motors. I put in a claim with them last year, 21 November 2023, they send out their service provider (Mr Technology) to come and replace the gate motor. This gate motor started giving problems from the first day of installation. The gate moves halfway then gets stuck, then I have to manually move the gate. I made the service provider aware, they returned and told me the problem was resolved. The gate did the same thing the next day, I again made them aware and had no response, I then reached out to Nedbank who instructed their service provider to come and fix it. Same story, it worked only 1 day and stops working the next day. I made both the service provider and Nedbank aware, they came out several times but same outcome. It's now April 2024, 5months later, and Nedbank is unwilling to get a new service provider to come fix the problem. I'm still manually pushing my gate that has a "new motor" I've escalated this matter countless times to Nedbank manager with no help.

My refence number with Nedbank: C***
