Burst Geyser Insurance Claim

I have submitted the Serial numbers for a burst geyser and the new geyser with the plumber’s damage report 3 times now, yet I keep getting a new request for the exact same claim time and again, each time from a different person. Standard Bank Insurance, your service is much to be desired. The geyser was replaced at least 3 months ago, next thing is you will be saying my claim is too late and therefore you will probably end up not paying my claim. I even sent a copy of my email to your complaints division.....no response!!!
