Are Our Assets REALLY Safe with Syfe?

I ACAT my assets from TD Ameritrade to Syfe in November 2023, and have been discovering disturbing issues with Syfe custodianship. Almost immediately in November 2023, I discovered all the cash from the ACAT was missing. And they resolved it. Then in February 2024, I discovered the AMZN shares were wrongly priced. And they resolved it. Then again, in March 2024, I discovered some GOOGL shares were missing. And they are still "working on it". To me, discovering 3 issues in 4 months with the exact same account screams something's wrong with their accounts management. Does anyone have such experiences too?
