Dissapointed Customer

I logged a claim with Momentum in April 2023. The claim was declined due to an incorrect report handed in by the assessor. i was told that they would only pay 50% of the claim which i declined. (not sure how they got to this) .I reviewed the report and corrected it and then was advised to get an assessor to redo the report. This was done and handed in and I was informed it was escalated. I thereafter waited a month and still no feedback. I called momentum claims and spoke to Agent Ayanda who advised that Samuel would call me in 2 days that never happened. I thereafter called spoke to Debra who advised me to speak to the Team Manager Asanda, I was advised she would call me back and still no feedback. It's been 5 months and still no feedback. What kind of service is this? I need a final outcome so I can take the necessary steps.
