Late payment of a claim

Very disappointed with how my claim has been handles by Discovery, sent all required documents in December, my claim has been pending payment since 30 December and I called on Tuesday 3rd to follow up I was informed I need to wait another 2-3 working days for payment to be released and on the 5th of January I follow up and the person assisting me escalates as their Finance team is the reason payment has not been released I now have to wait another 1-2 working days. Please make the payment before end of business today. Discovery service is always an issue.
