Horrible, Terrible service experience, poor and unproffessional

Guys I just want to warn people against insuring with this company. At this point, I am not even sure if this is a legitimate company or not. My mother had a life policy with them, and she sadly passed away in early January. Firstly, I struggled to submit a claim, no one was responding to emails and no one was answering the phone. Luckily, I was in Johannesburg at the time imagine if I was home in the eastern cape, I drove there, and I found two front ladies who said there was no admin staff around only them. I spoke to a guy named Tshepo on the phone, he gave me some half-detailed information about what I needed to submit. After submitting what he said, there was silence, after a month, I wrote again, only to get to be requested more information from her medical aid, I asked myself if I didn't check in, were they ever going to communicate this to me? Anyway, I submitted what they requested, but now this claim is over two months old and there is silence, when I checked in again I was told they would communicate with me in a week they are understaffed. The week has passed, and I have sent countless emails even to the CEO, and complaints department. No response from anyone. I need advice as to the next step to take, anyone with information about the insurance ombudsman please share it with me, including an attorney that might take up this case, as I am planning to sue this company.
