Frustrated iwyze client.

I made a claim three months ago. They have frustrated me enough. Up until today im not getting any help. It's been back and forth with them. They don't respond to my emails. Please assist me. I ask them to reduce my access and they reduced it to 3000 because I couldn't afford the one i had. Now few months ago I had a accident, I called and they told me my access will R6000 i told them i can't play that, I remember very well calling them and telling them I can't afford the one i had before. And they said i should have read my contract but I was not told. I ended up agreeing to that. They called again and said it will be 8000. I than ask for a recording because it was too much for me. Months, a passing while waiting I'm calling and sending emails. Only respond sometimes and for a very long time there is no response. When i call they say they will call me back. Two weeks ago I lost my grand mother, I told them I'm going to PMB in KZN to burry my grand mother. Spoke to them and ask to resolve the matter Aftr a week. I did that and I ask to fix the car in KZN. I told them the time frame. Nothing happend now I'm back in Jhb and I sent an email again. They not responding. The last lady I spoke to said i will pay R6000 than i said it's Ohk because im just tired. I want to get over this and move on. Please help me.
