Disgusted at the claims process

i Registered a Claim for My Geyser on the 16.07.2021 to date Nedbank has made no contact with me to date to explain any procedures regarding the claims process at all , a plumber rocked up at my house yesterday to do an inspection but yet again nobody told me of the process we are currently going through a 3rd wave of covid i have children at home and this person i dont know just comes and enters , i am really not happy i called the claims line twice now and nobody know what is going on or can give me feedback keep telling me to call here and call there for further assistance , i am seriously disgusted to say the least and i never would have thought i would get this treatment from Nedbank .
