I left Vodacrap 2 years ago, had no probs with them but hated how they changed the SW etc and everything was linked to Vodafone Live, in those days they stopped you using mp3's as ringtones, tho you can now.
Been with o2 since and I can honestly say I've had no problems.Last year, they let me finish my contract early by 3 months to get a K750i. This year, I rang them last week for my PAC, saying I was going back to Vodafone.I wanted the LG KG800.
Went thro to a guy called Andrew, explained everything, no problems with o2 but wanted a better deal. I was on on the o2 200, 200 xnet anytime mins and 100 txts for £35 per month. If I stayed with them, I was offered 500 anytime, x-network minutes and 300 txts for £20 per month,12 month contract and a free KG800.
Well happy, altho, they don't have any to send out till the 15th May....so I've gone for that.
And, yesterday I ordered a KG800,free on a 12 month contract @ £20 with £50 cashback thro
www.onestopphoneshop.co.uk total cost £190, will get that tomorrow, and my upgrade will do for my wifes birthday pressie
Regarding the PAC, I do it every year.....its surprising what you get offered. Always do it the first week of each month....thats when they're trying to reach their targets
