No Response from ABSA Insurance for burst water main

I have my home insured by ABSA Home Insurance. On Friday afternoon 16 May when I arrived home I found the main water supply pipe from the pavement to my house had burst. I immediately phoned ABSA Insurance to log the problem and was given a claim reference immediately and told a plumber will call me within 1 to 1 1/2 hours. I received no call. On Saturday morning and Saturday afternoon I made 8 calls to ABSA Insurance either to be put on hold or then put through to FOGI whom never answered the call (I have my cellphone call log as proof). It is now Sunday morning 18 May with again no feedback from ABSA. I just left a private message with the Drain Surgeon Plumbers whom called me back within 15 minutes and already arranged to have a plumber at my property within 2 hours. This is the worst service I have ever had from ABSA Insurance.
