Absolute shit they are. @Justmuddlingalong YANBU.
We had them from the mid to late 1990s, when they took over telewest communications, and they were OK for the first decade I would say. Then from around 2008, they started to get really poor. The service was off more than on, we waited half an hour or more to get through to someone, and would often wait a week for an engineer to come out if it couldn't be fixed over the phone.
We lost our TV channels too as we had the TV with them as well. Sometimes we lost our landline too. We had a mobile phone, but it was PAYG, (which was expensive at the time,) and a 30 minute wait for them would cost a tenner of phone credit!
I wanted to move to someone else for 4 or 5 years, but DH kept refusing which really fucked me off. They got worse and worse, and by 2012, the bill for internet, TV, and landline phone was around £80 a month, and it wasn't even including film or sports channels.
We moved to a rural area in 2014, and PRAISE BE, Virgin aren't up here. And they say they never WILL be, as the population is so low. So we were forced to go with someone else. Picked PLUSNET. 6 years on and we have got not one single complaint.
Only went down once, a few weeks after we got here. The BT lines were so old, that we were struggling to get any speed on the internet. So we called them and they came out 2 days later, and said the old BT lines needed them replacing. So they replaced them (free of charge!) and we were without internet and phone for 3 hours. No problems since ... ever.
We currently pay £33 a month for super fast broadband internet, and our landline, with a call plan that gives us unlimited landline calls, and 500 minutes to mobiles. And we have freesat TV, and netflix. Freesat was a one-off payment of £200 which we paid 5 years ago, and netflix is £7 a month.
I would NEVER go back to Virgin Media. They are AWFUL.
