I have recently experienced problems with my Q box not connecting and or not retaining my router password. Despite several attempts to resolve this including an engineer visit to replace the box, it continued. So today I called again and was connected to Engineer Aziz (in South London, I don't have his family name). I was on the call for over an hour but he patiently worked through various steps until the problem was solved. I'm not technically adept but it seemed to me his level of knowledge was excellent. Additionally, he was clear, friendly and very patient (see above, not technically adept comment). He didn't rush me and talked me through what was required. When it seems these days that customer service can be somewhat lacking Aziz showed how it should be. I hope this feedback reaches him. And that he is valued by Sky, he's a great ambassador of how it should be done.
