Sirago pathetic service

My dad was in hospital from 23/04/2019 to 17/07/2019, when he passed away. I have always been in charge of his medical aid and Gap cover, as he never had email. His Medical aid was with Medihelp and his Gap cover with Sirago. When the bills started coming in, I managed it and checked what was paid and what not. I sent in the accounts with a gap to Sirago. Some of the accounts were PMB and others were not PMB. Some of the PMB ones were not paidi n full, as the doctors were not preferred service providers. Sirago paid R30 000 (as per their rule) on these accounts, but did not pay anything for the ones that are not PMB. Every time I was told that I must re-submit the accounts to Medihelp and see what else they can pay from PMB. These accounts have been send back to Medihelp three times. There in now still an amount of about R28 000 outstanding that Medihelp says is not PMB and Sirago is refusing to pay. The lady I dealt with at Sirago, Althea Saunders, always promised to phone me and keep me up to date, but did not phone me once. She emailed me a few times, saying she was going to phone me the next day and never did. Whenever I phoned her, she was never available to speak to me. She only rep**** to an email once I got a broker to contact her and then she also only stated that they are not going to pay and it must be sent back to Medihelp to pay from PBM. I have sent it back and Medihelp confirmed that the outstanding amount is not PMB. It has been two and a half months since my dad passed away and I am still struggling to get this sorted out. My dad was good enough to pay the premiums, but now that there are claims, there are issues. I will never advise anyone to make use of Sirago as a Gap cover, as I have never received such bad service in my life.
