Dodging questions, no one knows what's going on

ABSA insurance at it AGAIN!!! I had lightning damage to my electric fence energizers and other security equipment. I had it repaired, lodged a claim, and submitted the documentation to ABSA. Eventually, after phoning them multiple times, (they simply do not answer my questions via email), they told me only one item on the invoice had been approved. When I asked why, what the reason was, no one can tell me. I have been phoning and emailing them (but they don't provide answers on my emails) but still no answers.
