No response to call logged for repair of Bosch gas water heater

<p>I reported a faulty 14l Bosch gas water heater on Tuesday 27 June (call no BJ056221). The call centre ( ********** 724) said a technician would be assigned and I would receive a call from him. I received no response so phoned the call centre again on Wednesday 28 June. I was told that the supervisor would assign a technician. Still no response so I once again phoned the call centre on Thursday 29 June and was given the same story/reason/excuse. This poor service is unacceptable as we have been without hot water for five days in very cold conditions in Barrydale. So I contacted the suppliers of the geyser on Friday 30 June, Give It Gas in Johannesburg, who said they would try to contact the Bosch service manager to get the problem sorted out. It's Sunday 2 July now and still no call from Bosch. The least I expect is a call from Bosch to say when/if the problem will be sorted out. The heater is under guarantee. POOR service!</p>
