Standard Bank Insurance's services are terrible

I have tried to follow up on a claim for my father for a long time. The claim is submitted end of last year. Standard Bank has not coming back to us after the assessor has came to assess. When we have made calls to the ********** 444 and after selecting the option, we just hear that they have high call volume. After waiting for 15 minutes or more, it then connects to a number where it just rings and rings but no one pick it up. This is not the first time which we have made claim but it seems that every time we have to keep following up and keep having to found ourselves wasting time and money on non-responce phone call and no one from Standard Bank insurance seems to be bothered. Extremely disappointed!!!!
