Horrible Customer Service

For Direct TV, I was charged for an early cancellation fee,  even though the agent who I cancelled with assured the cancellation was done correctly at the right time.  It's only $21.20, but I have now been on the phone with customer service FIVE times for almost 2 Hours total time, and it's still not resolved.  The last agent said check would be sent 3-5 days.  3 weeks later I call and am told it wouldn't be until at least 60 days after cancellation,   so. . . the last agent outrighted lied , or they have such bad supervision and training, they can't give you a correct answer.  This family will never purchase any ATT product of any kind here on out.    Do better.
