Treated like a *****

I took out a house content insurance with Momentum after I relocated to Port Elizabeth. I had a burglary at my house where ******* came into my house when I was sleeping with my kids. I phoned Momentum to report the case and to my surprise I was interrogated like I was the *****, they wanted me to prove that I had the contents I was claiming for. When you take out insurance you are not asked what you have you are only asked how much you want to insure the contents for now all of a sudden I must prove what I had and the interrogation was really something else. Me and my kids are traumatised by this incident and Momentum is just adding to the stress, if they want to treat me this way then I really dont see a reason why I should continue with the insurance.
