Shocking service

My husband passed away in 2021. Am trying to wind up the estate. I had to visit SARS and was informed that there is money outstanding. Investigating further. SARS referred back to 2 Liberty Policies. I was told by Liberty that the 2 certificate were cancelled this is not showing on SARS side. I have been sending emails to request the proof nobody responded not even the complaints department. This is shocking and annoying to say the least. Have to wait forever for information
