Poor service

I submitted an insurance claim on the 04 of May 2022 no one came to me I called them on the 06/05/2022 and I was told everything I needed to submit is there I waited on Monday the 09/05/2022 I called again only to be told I'm missing 1 page of notice of death I sent it , today I called because an sms stating that I needed to submit a printed death certificate I sent a letter from home affairs reasoning as why there will be no printed death certificate, I called again the sales consultant told me to hang on the line , then my call was transferred from one consultant to the other until I requested to speak to a manager who told me that they will not process the claim because there is no printed death certificate I told him there is a letter stating reasons and he responded that they will not accept it my question is where must I get it when I asked to speak to someone higher than him he told me there is no one higher than I must get the death certificate the service is so poor tht at some point a consultant heard me talking alone while I moved my phone off the ear looking for the time I sent the email voz she can't see my mail , she heard me saying this is really shut and she dropped the phone it's said that they rob us of our money every month and when you claim you must speak to the whole world I even called their head office where an instruction was given that they must contact me till now no one have contacted me
