I'm on o2 broadband, they are friendly quick & reliable..Also if you are an o2 customer, you get ?5 off your bill every month..check the link here i had probs with the mac code because no one could tell me who the isp provider was, bt were v unhelpful & rude,even tho it was their phone line, they made me feel crushed & devalued. Eventually, o2 told me that it was sky- it took ages to speak to someone at sky& about 2 weeks to get the code. (one week was finding out which isp we had previously)
