Bad customer service

I lost my power battery at my luggage on my return flight from cape Town to Port Elizabeth on the 13 September 2019, I reported the matter to the official of FlySafair he immediately opened the claim case and send me to the police station to open an case for lost item and 2 days later I received an email from FlySafair claim department informing that valuable items are not included in FlySafair but why the official wasted my time of filling up the forms knowing very well the valuable items are not covered he should have informed me that the valueble item are not covered instead of wasting time.

I need FlySafair to replace my lost items due to your official gross inconvenience caused.
