Poor Claim process (BAD SERVICE)

I am disappointed with Momentum Building Insurance, lodged a claim with them for hail damage and they made life a living hell for me, they do not communicate with me and appoint unskilled assessors who call you to make appointment and advise you that they can not tell you the date that they will come they will just call you an hour before they come without a suitable date agreed on, when they called luckily I was home because they did not indicate the date, on their report is indicating that they could not do proper assessment because they did not have access but they report says the claim is rejected, what a joke. To put salt on wound when I appeal the continue with their bad service on sending sms, without calling or sending email. I have never came across such unprofessionalism from a company called Momentum Insure. Through all these bad service I received I still cant talk or receive a call from Momentum to complain about the bad service I received I only got the report from the third part with Hope Machetele as a person handling the claim, who is unreachable but was handling my claim.
