Very poor service from Santam

We are without a car for 2,5 months. We had an incident over Christmas season, as you know, all the dealers were closed, and it seems Santam as well. So we took the first available appointment where we could book the car in for assessment. Since then, we fought with them. In short there is an electrical or mechanical issue on the car, since the incident happened. I've got no mechanic or electrical background. All I can say is that from Volvo and Auto lab side there was a lot of assistance, regarding our vehicle's reports. According to Volvo and Autolab's reports the 2 computer boxes are not communicating with each other, so there is an electrical problem on the vehicle and Santam said it is not accident related because we still drove the car for a day or 2 and then it switched into limb mode. Even if the computer box being reset it will work for a few meters but then it will switch into Limb again. They only want to fix the car on the outside but what about the boot and sensors that is also damaged in the accident and any nonphysical damage and not working, this is electric. They say they can do more tests, but the client need to pay or proof that it is accident related - it will be for the client's account. They can see there is damages to the electrical components, but very limited. Volvo told us directly that the car is too old to do any further inspections and need to be stripped for more reports. Volvo drove the car to find out what is wrong with the car, according to them the car changed gears easy. Now Autolab say the car is stuck in 3rd gear. We understand the contract, that say that Santam will not pay for any maintenance, but this is not maintenance it is a problem on the vehicle that happened with the incident. The car was serviced just before the accident and everything was still running smoothly with the car, with no problems. Santam just keep on saying that the electrical is not part of the accident. Now we are sitting without a vehicle in this "Tennis Match" between all parties, they are not even communicating with us further on this matter, we tried to phone them the entire week and asked them to return our calls, but nothing. We also asked the assessor to visit the premises to see and understand what the impact on the car was, but no one communicated or visited this premises yet. Santam send out people that is not knowledgeable on vehicles, I believe that was just to keep us quiet. The lady that sold us this policy keep on recommend the ombuds, what we found out lately is that there is a protocol to follow fist, but this was not offered to us to go through that channels fist, she recommended the ombuds way in the middle of it. I will never advice or recommend Santam to anyone. We request that they contact us urgently so that this can be resolved now once and for all. I had to ask my father to take it further on my behalf because I stutter too much.
