Why should NTL give you a deal and not everyone else who pays the £24.99 for the 2mb connection.
1st for you to take up ADSL you need to pay the activation fee almost £40!
If NTL are going to do these deals for one then everyone should be allowed the deal, treating one customer differently just becuse they threaten to leave is wrong. If they want a better deal then NTL need to look at their overall pricing and devise the best price for all. If that is reducing the prices to £17 then so be it.
Which ISP was you using to get the price reduced as all £17.00 ADSL packages are capped ones and if I remmeber correctly capped at less than 30 gig a month.
I could go on looking at more if you go uncapped its more like £30 for a 2 Mb.
If you are going to try and bargain a deal then you should match like for like which at the price you quoted you didn't. If you have the BB that cheap NTL should also cap you at 2 gig a month.
