Non-responsive to Burst geyser

My geyser burst yesterday and I called the emergency number for momentum. They advised me that claims is closed and I should call on Monday (today) at 8am. Okay, fine so we closed our main water line for Sunday night. This morning I have spent an hour and 7 minutes and R200 worth of airtime calling the *** number. I got through 4 times. All four times I was told the consultants are busy and they will call me back. they took my number down and I am still waiting. 2 hours to return a call? I have a family and we cant wait forever for our lives to continue. I am now instructing my plumber to go ahead with the geyser replacement. I have tried the prescribed avenues to contact Momentum to get this claim going… But I have been met with no response. Please contact me.
