The cable TV at home didn't receive any short message, indicating that it didn't buy this program.

You can't solve the problem of not buying by yourself. Generally speaking, this is due to payment or this station is charged separately, in addition to the monthly TV fee. If the payment is normal and this channel is not a special charging channel, you need to re-authorize your set-top box card number.

All the premises are that this set-top box must be distributed by local cable TV. If not, they won't give you authorization, and you can't even pay.
