I don't work for THREE but want to say how happy i am with my tarrif and handset....
I work in the customer service industry and good service is NEVER rewarded, but i gotta say, three have been badly (and rightly) critised in the past for offering poor customer service....it seems they have been listening.
My reason for going with three is that they actually have a shop near me in Watford so i guessed if i had problems and couldn't get them resolved i could go in the shop and give them what for....Never had to do it!
My three xseries is the BEST tarrif i ever had...unlimited skype, browsing, loads of mins and thousand texts, TV if i want to pay for it..allows me to make FULL use of my N95 (bought sim free) upgraded from the N73 i got from THREE, been with them 9 months and having heard all the horror stories of what Orange and others do to their handsets, not looking to leave.
