Lack of communication

On the day I took my car in for service. I was told that there’s an issue with my liquid capital policy. I was told that I had missed a payment for the previous year for September. The problem with this is that I received no communication from Liquid capital in the month of September and October regarding an outstanding payment. I had to pay the outstanding balance right then and there to get my car serviced. Fortunately I had the funds to do so but what if I did not have money to cover the outstanding balance. Would it really hurt to send a mail or a message that there is an outstanding payment so that it can be addressed. Rather than waiting for the customer to take in their car and find out then about an outstanding payment. Truly thought this was unprofessional on their side.
