Answer:
Communicator miscommunicates what they are really trying to say, and/or the hearer misunderstands and mis-interprets what has been communicated. It is important to remember all sides of a communication breakdown, those who communicated and those who were communicated to. Sometimes they are clients, sometimes they are staff. Whoever is involved, it's costly to let it continue, especially once it has been identified.
Be patient. Communication breakdowns are frustrating, and leading out of them is hard. Without patience, it only gets worse. If you don't believe me, just give it a try without patience. A lack of patience is usually what created the mess, so unless it gets added to the mix it will only get worse.
I hope this helps you dig out of any communication breakdowns you currently find yourselves in
