Bad service and bad customer face to face

A Z3 only one month old today has water damage. Imagine my surprise, A water resistant phn that has water damage and Sean from Telkom tells me its not a water resistant phn and I will have to pay for repairs. I asked to speak to a Supervisor and she was not available at first. The Manager Aletta Clark has left already and they could not help me that was at 4:05pm and she will only be available next week Wednesday. The supervisor finally came(Nomsa) who said that there is nothing they can do. I was was turned away with the damaged phn and no reference number for my query. I demand feedback before I take legal action against Telkom.
