Years ago we did business with a company and their form *required* a phone number. I asked them several times to only email or text, but they called anyway. Now they've got a new representative, who promptly tried to call me (but failed, probably because my phone had no power). They sent mail; Spouse mailed back "please don't make voice calls, we prefer email" -- but today they called. On my private number. When they've been asked SEVERAL TIMES not to do that. I think it's time to block them.
