up and down

i was involved in an accident on the 9th of September 2018,a claim was lodged and it was investigated by Mr Adriaan Venter who after 2 weeks of getting all information from me disappeared and never phoned me.the third party insurance phoned me asking for details of which I gave and they also advised me that since the third party admitted on the scene that she actually caused the accident tht will mean my insurance can claim from their insurance, I waited for another 2 days and started phoning mr venter and his fone was always on voicemail.i spoke to call centre stuff and told me in my case I can speak to Mr Hendrik who happens to be Mr Venter"s manager. they gave me his number but he does not answer his fone and he is always not in his office.on the 10th of 0ctober I spoke to Mr Tjaard Steyn who promised to wrap up the claim by 11th 0ctober and he promised to phone me back and he did not.on the 12th I phoned again and spoke to Mr Steyn and asked him wht was going on. he then told me that Mr Venter is sick and my claim was handed over to a Mr Giles Chuma after he told me he was wrapping up the claim on the 10th. Mr Steyn gave me numbers ********** which belongs to the Mr Chuma.i tried foning him his fone is also off. please help because I just dnt know where to go
