funeral cover claiming a nuisance

i submitted my funeral claim on the 31 January 2023 for my father in law whos funeral is on Saturday,i have to phone everyday to find out how far the process is just to hear that i did'nt do this or that,other than that they'll wait for you to contact them in hope that you don't ,they don't acknowledge any emails you sending them they dont reply or communicate with you,i phoned again this morning from my cell,they just acknowledge recieving my bankstatement that i send twice to them,now its gonna take another 2 to 5 working days from today,pathetic,no communication whatsoever
