I called KCTC the middle of April to cancel my cable services, so that I would not be billed for them in May. I was told you had to cancel before the last day of the month, so that you weren't an active cable customer the 1st day of the next month, to avoid being charged the entire next month. At that point, I asked what my bill would be for **** for just internet service. I was told $105.94. I was doing my checkbook last night and found they charged me $275, as if I never canceled my cable service. I called this morning and was told that I would've had to terminate service several days prior to April 30th, because they do their billing before that. All they offered me was a credit on my next bill. They won't cut a check, because they only cut checks on certain days. I am paying 2 bills late now, because the extra $170 taken from my account would overdraw my account. I was also planning on that extra $170 for a hotel room at a relative's wedding. I now don't have the money for the room. I feel this is completely unacceptable, that all they did was apologize and say they will credit me next month! For some, $170 may seem like chump change. For me, who lives pay check to pay check, it's a lot of money. This is how they operate though. My parents terminated their cable service April 29th, and they didn't get charged their former monthly amount. So, why am I charged/treated differently?
