Unhappy Customer

This friday my car broke down, called for assistance and only to find out that my account is in errors which I had no idea of it, because the last debit order had went through. The 2nd agent told me that I cant be assisted and had to pay and additional amount. I then asked her to then add that amount to my monthly debit order and I get assistance, which in turn refused. I had no means of making electronic payment at that time. This was gonna be avoided had they made me aware that I was behind and resolved that matter. I had to sleep in a car because I was not assisted. After everything am a paying customer, having a road side assistance policy with the company.
