PSG ********** service failing to honor a minor claim

I have never experienced such ********** experience with PSG insurance, I had a Gyser issue which they said the fault wouldn’t be covered if it’s more than 10 meters away. I called two electricians after Cornel Janse van Vuuren who works for PSG had promised that I would be refunded the money paid to the electrician if the fault was on the Gyser. My electrician confirmed that the temperature was set low which resulted me in not having water. Now PSG does not want to honor their end of the agreement by refunding me what should initially be covered by them. It’s companies like these that give insurance companies a bad name by failing to honor claims, even minor claims of this nature
