BT and Sky - a study in ineffectiveness

I have a BT (British Telecom) phone line. When I signed up with the satellite company Sky, they offered free evening and weekend calls on my BT phone line.

Today I got a BT phone bill with THEM charging for those very calls. I phoned them. There were long queues and a call-back facility. I opted for it. Fifteen minutes later I got the call-back. She had to pass me on to someone else. OK. This person had almost lost her voice (ideal for answering queries on the telephone). She said she had to contact someone else. After a few moments of awaiting her return, I found I'd been put back in the queue. I decided after a few more minutes to hang up and try Sky.

After more than 30 minutes of "We are sorry you have been waiting longer than we would like. Please hold the line till an operative is free to talk to you," my meal was ready and I hung up in a second wave of disgust.

I have emailed both. The automatic reply says Sky hopes to get back to me within FIVE DAYS! Superquick, then. Did you people want me to change my broadband account to you? Apparently not.
