I gave retentions a call as having done some research on alternative providers, NTL weren't matching up well pricewise at all against Sky.
I spoke to a very pleasant and helpful lady.
My earlier NTL retention offers having expired I was paying £66.50 pm (up from £51.50 for the previous 6 months) for
2mb broadband
Family Pack tv (I think this is XL in the new terminology)
Line rental
Talk Weekends
Sky Sports
After the call to VM retentions I ended up on a new package. £52.50pm for the same package plus
Sky Movies
This works out cheaper than the Sky deal for the same package. So I saved £14 a month and gained an extra premium tv package. Now I just need to find the time to watch it all.
Note that I didn't at any stage threaten to leave, just pointed out that what I was paying was not value for money compared to Sky. I was then offered the new package, non-time limited, no contract to sign, no need to ring retentions every few months.
I'm sure people will be on "better" packages than mine, but this one suits me perfectly. I just hope they can get the billing right.
