Oneplan Health Insurance
Awaiting more than 3 months for claim to be paid

My late father was in hospital the 14 and 15th of May (Kuilsriver hospital), we've been submitting the invoices and so the different doctors. My mother is getting demands on the bills already. I've been chatting on line with Happy that is trying to assist, but really how can you say a hospital bill can take 30days and its more that 3 months already. No returning emails. please can this be sorted out. My father passed away the 1st of July and still my mother must get this bills.
