My question involves business law in the state of: TEXAS
I sent certified letters to companies letting them know I will be charging X amount of dollars for each call after a certain date, and the payment due date.
One company continued calling with no intentions of honoring my terms, they were determined to keep my calls free. I was under the impression sending the certified letter stipulating when the charging would start, the cost of the calls, and the payment due date was sufficient. Did they not agree to my terms by continuing to call?
