best isp with uk calls?

[AtomicFuse]

Hi all, I was wondering if any of you could help me. BT have tested my patience too far with their unreliable service consdiering the price, and I think it is time to switch.
I am looking for uncapped or at least 5GB download limit broadband (preferably 2mb and up) with calls to the UK included, so I don't have to have any new hardware or line rental with BT.
Any help would be much apreciated!!
Regards,
Atomic
