Hi, I want to order BT Infinity using BT's website and get Quidco cashback. Currently my landline and calls are already with BT. The broadband with Sky. So.... my question is... when ordering BT Infinity online, do I click on one of the packages that includes calls? Or do I somehow just order Infinity on its own because I'm already on BT calls tariff? Grateful if anyone can advise with their experience as I don't want to mess up the cashback.
