But the law does not say that. As a matter of fact there is no legal limit in Federal Law as to how many times they can call you. There is a time limit of 8 am to 9 pm your time.
Now, if they leave a message or talk to you it is regarded as first contact and they now must do this:
Federal law (FDCPA) requires them to send you a letter (US MAIL ONLY) postmarked within 5 days of their first contact that contains their name, physical address, the creditor’s name, and the amount of the alleged debt. It also must contains “mini-Miranda” telling you that it is an attempt to collect a debt and that all information will be used for those purposes. The one other important thing that this letter must also have in it is that you have a right to dispute the debt within 30 days of receipt of the letter and if you do so, all collection activity must be stopped until the debt is verified.

Debt collector. They don't leave messages so that they can call you multiple times a day until they get someone to answer. Law states that they can only contact someone once a day. If they leave a message, it counts as contact.
