I might be the odd one out here, but I was pleasantly surprised when I finally phoned up Virgin about a broadband issue (it was cutting out on me once or twice a day.) I'd been putting off phoning them because I was expecting awful customer service, but I was only waiting about 5 mins, the person I spoke to was quite helpful, engineer was out a couple of days later and replaced a bunch of cables and the connection box. Early days to see if it's resolved the issue, but they've put the effort in, to be fair.
