What should I do if a school still has not received my ED agreement form and the deadline is the 24?

So I was not able to send it in before the Jan 1 deadline but the school told me it was okay to send it in late. I gave the agreement form to my counselor on the 3rd and I got an email from the school this week saying that they still have not received it. I went to go ask my counselor is he had sent it but the assistant in the front said he was too busy and told me they sent it on the 5th. The college emailed me asking that it be submitted by the 24th. How long does it take for colleges to receive forms? Also, should I call the school and ask if they have received it even though it says they didn’t on my account?

I would call.
