Very poor service handling my claim

After a claim was logged it took three weeks to take a decision. A week later and still no one informed me about the decision. Regarding the claim: only one quote was obtained from the assessor. During the second week of the claim I also sent an additional quote from another service provider to the assessor which was just brushed aside. According to my knowledge the assessment was not done properly. To crown it all, my property is under insured. Now Integrisure tells me that I can get the value calculator on Santam's website. A year ago when I approached them for cover none of this was divulged to me. I've calculated the value according to the values that is given on EstimationQS for freestanding houses in Gauteng: R6102 per square meter. With this the value I've insured is correct. Just yesterday morning Integrisure said in an interview on "Die Groot Ontbyt" that they ensure that there clients are not under insured. Is this perhaps the way they do it? I've asked the consultant that phoned me to tell me that the assessor will phone me to discus the settlement that I am not happy and that someone from management should call me. They did but could not answer my questions and did not have all the facts. Why phone me then?
