Complaint Review: Dish

Please watch your Dish bills. Dish TV has recently changed their billing period and dates. the result is the customer being charged 13 monthly payments in a 12 month period in 2015. We were receiving the bill at the beginning of the month from Jan to Aug. Dish decided they would change their billing to the end of each month and it would reflect an 'in advance' billing period. The original billing date would fluctuate a few days at the beginning of the month. We made a payment on aug 3, and then another on aug 27. Their representative told us the first payment (8/3/15) covered jul to aug billing period, The second payment (8/27/15) was to cover sept to oct billing peroid. They then wanted another payment in sept to cover sept to oct, etc. No matter how they cut it, it looks to me like I'm paying twice for a billing period. When I pointed out that in December I will have made 13 payments in 2015, they simply stated that although a payment will be made in December, it is a billing for the month of January 2016, irregardless, it will be the 13th payment. I then pointed out that means I will still be making 12 payments in 2016 to which they really didn't have relevant response.
This looks to me like creative accounting simply to boost profits.
