Clear case of overcharging

The company came out to investigate an issue with my GeyserWise setup but were unable to diagnose the actual fault. Instead of troubleshooting properly, they simply quoted me for a full replacement of the main controller at an exorbitant price.

I later had the issue resolved by a local plumber at only a third of the quoted amount. This proves that their recommendation to replace the entire controller was not only unnecessary but also a clear case of overcharging.

This approach is unacceptable. I strongly suggest the company invest in proper GeyserWise fault-finding training. Quoting clients for a full replacement without accurate diagnosis is nothing short of exploitation. I have also reported this matter to my insurance provider.
