Unsatisfied client and very poor service

I registered a claim after storm damage at my house during December 2021 whereby water was leaking through my roof and caused a lot damage in my one room.The heavy rain and wind damaged one part of my roof.I got a quotation from a building contractor which amounted up to R42 000 to repair the damages.This was done on recommendation by the assessor when he visited my house to assessed the damages.Three weeks later I had to phone the assessor to request the status of my claim because he didn't had the decency to give feedback after I submit the quotation to him with all relevant information.He then inform me that the quotation is to high and will send out a contractor for another quotation.After a week the contractor pitched up and a few days later my broker contacted me to sign a document for payment of my claim.The contractor which the assessor send only quoted about R5100 for painting inside the room because he said the rest of the damages is caused by myself which is ridiculous. I have to mention that during November 2021 I had to repair the roof myself also due to damages caused by heavy rain and strong wind.I did it to try and prevent damages.It cost me more a less R10 000 out of my own pocket and did not registered a claim. With the second damages in December which was more worst than in November I had to register a claim with Old Mutual Insure and now I can't repair the damages because they don't want to pay for it. My claim was registered by 7 December 2021 and it took them more than 6 weeks to finalize it.Later in December the damages increase due to heavy rain again while they showed a non care attitude in handling my claim.I'm so dissatisfied and disgusted in the manner they handled my claim and I even lodge a complaint with their complaints devision.They didn't conduct a proper investigation but only concur with the assessor. I now have to reconsider my insurance with Old Mutual insure and will definitely recommend this company to anyone because if this is the way they handle clients for such a big company then I really don't know.
