"Touch wood" if you would involve the same problem again, unless you are in the legal profession and if that is part of your job.
I do not have the Malaysia legislations in my office. I am not involved with this area of law.
My feeling is that you were in an excellent position to get RM150 a day and I think most people in your situation were denied of this claim. If you are really bent on seeking the relevant legal information, you may visit the law library of Universiti Malaya which is charging about RM20 a day for the usage. Of course you can always seek professional advice from the legal practitioners. Many of them do not charge for the first brief consultation. Since your claim amount is rather substantial in comparison with the legal service cost, you may well consider whether to engage your own legal representation to ensure your interests are best protected.
As a passing remark, keep a good record of all your communication with your insurers. This may be very useful for evidence in a court of law. Lawyers for the insurers commonly shift the blame to the insured for not furnishing the repair costings promptly and take issue over the suitability of the repairers to minimise their liabilities.
