Still not help

I have been trying for this past week to get help form Nedbank,the Ombandsman and halopeter.com as Nedbank is still refusing my claim for the geyser. Now Nedbank is saying that I cancelled the Insurance and that a debit order was not received for the Insurance. I requested for all correspondences, letters or emails as evidence where I was notify or where I cancelled anything. No luck so far of any assistance from anyone and in the meantime I am still without a geyser in this icy cold weather.
