Three months later still having the same problem and no response

This is the third month since I filed a claim for a burst pipe. The geyser people came and changed something on the geyser which had no problem. After that the geyser started shaking violently and spraying water out of the roof. This was wasting water and also keeping us awake at night. I contacted Standard Bank insurance and they sent someone again who changed a pressure something. That made things worse as the water started shaking more frequently and spraying water out. I sent Boitumelo who was dealing with y case an email explaining. I even took a video of the water spraying out an audio of the geyser shaking. A week later I haven't had anything back from them Sent another email to check and still no response.

Here is the email I sent explaining. "Hi Boitumelo

The plumbers came and they said the geyser is not bust and they changed a pressure valve or something. Unfortunately this hasn't solved the problem. The geyser is still shaking and making noise. Nothing has changed. Looks like its getting worse everyday and now it happens every hour or so. We can't even sllep because of the noise.

We are also losing a lot of water and money. This month's water bill was around R3000, can't imagine next month.

Check the attached video and voice recording. This is costing us a lot.

Regards"

Can someone please help.
