Wells Fargo Credit Card Complaint

Wells Fargo Credit card department,

California

My credit card company, Wells Fargo, does not state an end of a billing cycle date. I have been told by customer service that the billing cycle is 30 days, most months. Since Wells Fargo does not list which months will not have a 30 day billing cycle, I do not know the exact date of the end of a monthly credit card cycle. By not disclosing the exact end date of a billing cycle it is difficult to manage my expenses.
