How a Business Hired a Lawyer to Draft a Transportation Service Agreement in California

This appears to be a breach of contract. A breach of contract simply means that one party was obligated to perform and they have either not performed or have said that they will not perform. (Restatement (Second) of Contracts.) This applies regardless of whether the agreement was written or done orally. Typically, the aggrieved party is entitled to be returned to the same position they were in before the breach. This means that if they were no timely or reliable, and they have consistently failed to meet the service levels, and it has caused disruptions, then there is a breach. The quicker, informal option is to send a demand for performance. Performance is the payment of some money or engaging in some required action.
