Poor claim submission process

Submitting a claim is close to impossible at budget I have been struggling for more than a week just to get a geyser claim sorted. Firstly the link on the online portal doesn't work even if you fill all info they its still says claim info incomplete and they done bother calling you when they see the system says incomplete. I decide to call them to follow up and they have been giving me run arounds I am on the 5th person to assist and no one can assist. I do not understand how complicated a geyser claim can be.
