I live in a small town in California and recently sent in my payment for utilities (water, garbage and sewer). The bill was due on the 9th and I mailed it on the 6th. I just got a bill in the mail for $25 stating that I paid late. The total of the original bill was $65.
Is it legal to charge a 40% late charge for being one day late? Can I prove that I made the payment on time if it was sent in the mail?
Thanks
