Openview Dish Installation - Kevin ***)

Makro recommended that I use a guy named Kevin ( ********** 984) to install our Openview dish at our guard house. I unfortunately don't know his surname, but Kevin was quick to install our dish and take our cash, however his after sales service is shocking. Not long after the installation we lost signal. When I contacted him he blamed the trees for the weak signal. If this was an issue, then why did he install it where trees may impact the signal. We have not had signal for the past month. Please do not use Kevin ( ********** 984) to do any installations.
