No response from Sanlam Trust, after multiple calls and emails

Sanlam Trust in Lynnwood, Pretoria, was the executor of my late wife's estate in 2017. I now need some documentation regarding the estate from Sanlam. The original executor has seemingly resigned, but it is now impossible for me to get hold of Sanlam. Their numbers of their Lynnwood office, which are on the internet, don't work. How amateurish - a large company that cannot be contacted.

I then phoned their general call center and was promised via email that somebody from the correct department would contact me. More than a week later, nobody has bothered to do so. I then lodged a complaint on Sanlam's website, 3 days ago, also no response, needless to say.

They were extremely keen to handle the estate when they could get fat fees from the estate, but today, they simply do not respond. I would advise anybody who is considering Sanlam Trust's services, to steer well clear. To say their utter lack of service is execrable, would be to insult fecal matter.
