In my extensive experience, telecoms companies give very poor service - they're hard to get through to, and rarely do what they're asked to do right first time, leading to lots of time on the phone and frustration getting it rectified. Yay.com are different, wonderfully different. I signed up with them for all my business phones years ago - and they've served us brilliantly ever since. So now I've signed up with them at home. They gave me the same great service even though they're clearly specialising in business systems. They're helpful, friendly, professional, knowledgeable. And they handled my queries quickly and successfully. I highly recommend them.
