Faulty geyser

I would like to share the most disgusting service my dad has experienced with Santam... he lodged a claim for his geyser, on May 3rd claim was authorized on the 7/05/18 ... more than 5 plumbers have come through MDN plumbers, B& S Plumbers, PJ's plumbers, Zip plumbers, kwikot geyser supplier and the like all have no idea to sort a geyser... the geyser leaks a bucket of water every 45 minutes... my dad has been calling Santam on a regular basis and they kept sending a service provider who failed to show up and or failed to do the job correctly. So I called Santam last night 23/07/18 with the hope that they would take the initiative to sort this mess out ... one would think that this matter would have been a priority... totally unacceptable levels of service ... for 2 months it has been going on... wastage of water in a drought ridden country... why is this claim been taken so lightly and why are the service providers not held accountable for the shoddy workmanship... Santam this insurance is far from "Good and proper" you have let us down and we will definitely be looking to change our insurer!
