jimgriff,
I can fully empathise with your situation. Personally BT are not allowed on my premises.
However, I don't know where you are located. I am thinking that you have other options perhaps ?
I choose cable now as it's a proper DSL product. BT offers only ADSL and contrary to what everyone says it a totally different product.
I'd personally go cable if you are able to do so. I was initially on ISDN and it is a disgrace that one has to convert back at the cost of £50 in order to go Broadband with BT.
More information is required before I can comment further and I am sure others will have their opinions.
Pricing of Broadband in the UK is now getting better. However, I would seriously advise against going with BT. They will mess you about and pass you from plliar to post with their Billing system.
The cable system works well, it delivers a DSL product which does exatctly what it says on the tin.
There's no contention ration which is what BT seem to try and hide.
Sorry, but a bit of a very sore ex BT customer.
