The (lack of) speed of your responses to me - by email - suggests otherwise.
I'm not part of the support team (so I wasn't the person who answered your query), but I think a response within 24 hours via email is very reasonable.
I think that if a real response is going to take longer than a few minutes, then an immediate,
personal acknowledgement is in order.
We're living in the 21st century, and email is basically immediate.
While 24 hours is in some ways not unreasonable, in other ways it's a very long time, and something more immediate - but more personal and less condescending than a "dear valued customer" needs to be put into place.
For issues that need to be addressed faster
We're talking about a TV guide, aren't we?

What I'm seeing is partly broken ... requires prompt, but not immediate, attention.
Basically, the widget issues seem like poor QC to me.
Likewise, the Eye-TV issues seem to come under the QC heading as well ....
