Nedbank claims and customer satisfaction

Day 1 - Burst Geyser. Lodge Claim. No plumbers came. Day 2 - Plumber come assess after lunch time. No replacement unit. Nedbank refuse to make alternative plans for the client. Plumber says it will take several days. Nedbank expect their client to not clean themselves for over a week. Already receiving complaints at work that I smell. I have no alternative solution or family to help me.
