Rather than fix a false claim against an honest company, you have chosen to double down and defend your false claims. Even your anecdote about the March 7th doesn't hold up to 7-10 days, not be 2 days on the short side.
If, instead, you chose to fix the error and be not only honest with your customers, but also honest with your supplier, we would not be having this conversation.
This is a major red flag.
