WPP Content Producer interview questions

Was brought in for 2 in-person interviews, the last being with the CCO. Before I even got home from my last meeting, I received an email telling me not to take any other offers and that something will be worked out quickly. I interpreted that to mean an offer was forthcoming. After several days of silence and me poking around, the conversation became vague and I received a form email about a week later saying I didn't get the position and that I was a runner up. This is by far the most unprofessional interview follow-up I have ever heard of.
