AT&T AT&T DirecTV Satellite service AT&T charges full month for partial month's service Dallas TX

I called AT&T DirecTV to cancel my service due to being unemployed during a pandemic and the bill being over $220 for years.   Service was disconnected 7/21/2020.  However, the rep told me that they would not pro rate my final bill, which means I will be paying for 2 weeks of satellite service which I will not receive.   So - during a pandemic, after telling the rep (truthfully) that I had been unemployed for months, which was why I was cancelling service, AT&T Policy is to charge customers for a full month regardless of where their cancellation date falls in the billing cycle.   Apparently, this is perfectly legal.  I consider it FRAUD.  Can you imagine how many millions of dollars AT&T is swindling off its customers?
