As a professional with literally hundreds of millions of dollars on the line when we do deals, I absolutely insist on written records of communications especially if/when things go pear shaped. Please read my post above about how the ability to go back to a written record is vital to resolution of conflict.
Amos themselves has benefitted from the fact that the pre-sale comms were via text/email and she can refer to them to make her points.
When we do do things via phone call/zoom, 100% of the time I circulate a written summary of the call with all discussions, decisions, and open questions/next steps memorialised and request all participants to confirm or correct the contents thereof. But it’s much easier to just have it happen via written record from go. Then there’s zero chance of ‘Oh, you forgot to summarise this and I forgot you forgot when you circulated the summary.’
Yeah, no one has time for that nonsense.
Insistence that a phone call is the only legitimate reaction is antiquated and, I say this not to be mean but just factually, fairly unsophisticated in today’s world of transactions being conducted across time zones and markets and among people with different language abilities.
If all you have is a phone call, all you have is he said-she said, unless that phone call was recorded. See, also, my example above. The minute I knew this man was shady you could not have paid me to have a phone call with him. Whatever he said, he would have denied later.
Written comms are vital in professional transactions, more so when a lot of money is involved. Good luck proving that you agreed/didn’t agree to or disclosed/didn’t disclose XYZ when all you have on your side is, ‘This is what I said/they said in our phone call!’
Tone and emotion are more unpredictable in verbal comms, too. From the way buyer is talking here (you have no ethics; adults make phone calls; etc. - echoed by you referring to people who prefer written comms as not ‘adult’ and ‘human’) I would suspect getting on the phone with them would quickly escalate into accusations and highly emotional expressions. Better in those cases to stick to something less immediate and emotional like written comms.
