Liberty - Don't want to pay claim

Bad Service. Doesn't comeback to you. Phone calls being put trough different departments. No one wants to help. I did take a Retrenchment Protector benefit policy with Liberty trough Solidariteit Financial Services. After being retrenched I put in a claim. I sent trough all the necessary documents as requested by Liberty. The claim was approved in January 2019. State that the claim would pay out during a six month period. Which is fine because the policy documentation also state that. The first payment was due end of February 2019. 1st problem. Liberty need doctors details that were submitted in documentation early January. Only paid out 4th of March. The second payment due were end of March 2019. 2de problem. Liberty are waiting for doctors report. Only paid out 11th of April 2019. The 3de payment were due end of April 2019. It is now the 16th of May 2019 and I have not received the 3de payment. 3de problem. The policy is under investigation for a burn that I have receive while cooking (Doctors report). Why is the claim been approved? But Liberty stil have questions. Doesn't the paperwork been dealt with in January when Liberty approved claim? It looks like Liberty is looking for a reason not to pay the claim. But Liberty is fast to take the premiums debit orders. I am fed up with bad service.
