Non payment by Miway insurance

I am still struggling with the claim from Miway insurance of my car that was strike by lightning on 31 December 2024., I was not updated of the progress of my claim I kept on phoning them all the time about what was going on and they would tell me that they are attending to the claim until my car was deemed a write off beginning of February when they told me that the car was insured for R377 900.00 and R5000 excess amount will be deducted from the amount,they will pay R372900.00 to the bank after receiving the settlement letter. It was quiet for almost 2 weeks until I enquired why there was nothing happening,they told me that they were struggling getting a settlement letter from the bank,I had to ask for a settlement letter myself self from the bank and I emailed to them and they acknowledged it's receipt I waited again for more than a week for payment there was none.I had to phone them again they told me the settlement letter is expired now, I told them now the ball is in their court because I didn't give them an expired letter they let it to expire,they must ask for themselves from the bank because anyway I was just doing them favor because was their duty to do so. It went on and on without them contacting me and I had to contact them and get a different person until on the 25 th of March I was phoned by one of them giving me the same figures as above that they will pay the bank and deposit the difference in my current account within 2 to 3 days time.The 25th of March was on a Monday.I expected the back to be paid by Wednesday or Thursday but instead I got another call and email from Miway to sign that the amount was different from the previous amount that I was told by about R12000 and was requested to sign that I agree to it. I refused and asking them why it changed but could not get an answer but told me to contact their dispute resolution department of which I did but also got the same answer I asked them to send me their recorded message of the 25/03/2024 at about 9am they did send me so I told them that I am sticking to that message,I am going to sign the email that is containing the figures they sent before the 25/03/2024 and also on the 25/03/2024.I am no going to sign anything more or less than that. Now Miway has not paid till today and I am still paying the car they took at the bank every month and now I have to pay for the disc before end of May because the disc ic expiring.I am very frustrated to the point of death
