Installation gone wrong

want to share my disappointment with the onboarding experience I had with your company.

Initially, I had an appointment with your technician where I was informed that someone would call me on Saturday morning, July 12th.

Unfortunately, that call didn't come as expected. However, I was eventually contacted, and on July 16th, the technician arrived at my place to begin the installation process, which took more than 3 hours.

After they believed they had completed the installation, my brother needed to use the car for errands and noticed an issue with the Radio cluster.

He noticed that the Radio cluster is not working and is completely black. We called the technician and they came back and they worked on the car again.

Eventually they didn't manage to sort it out. I was told they will continue the next day which is 17/07/2024. Indeed they did arrive at my work place to continue their work. The technicians dedicated the entire day to despite our technicians' efforts, the problem persists.

I must say that this is not a promising beginning to our relationship. It raises concerns about the technician's abilities to install the products effectively.

Since the issue remains unresolved, I will take the vehicle to the dealership for repairs. Your company needs to cover the cost of the repair?
