Mobile phone stress!

OK, now I am totally pissed off with O2 and this fucking Nokia N73!!!!!!!!!!!! It keeps stalling and I keep chargin it up but it makes no difference. I thought it was gonna be the best phone ever for me as it has special bloggin tools - but I can't get them to work... I'm not sure I'd use this function anyway as I don't have anything going on (or anyone to share stuff with via mobile)... The camera is good but the lense cover is poor and rattles in your hand. It's bulky and doesn't look nice and the keys are badly designed... I've had enough! And I can't get through to O2 to sort it out - well, I did get through but was promptly cut off - which I hate! I'm thinking I need to go to an O2 shop or just cancel the whole order. If I stay with them I'm gonna have to pick another phone as I think the phone itself is not up to scratch, which is a shame cos I like messin with smartphones. I had one before - an Orange SPV E200 - which was fun at first but was bulky. I'm thinking about going for a Sony Ericsson K800i for the decent camera but I also want one that will act as a decent MP3 player and one that is designed well. There's also the Samsung U600, which can come in red (which would please me) but not sure O2 would be able to provide that colour, though I did manage to get them to get the N73 in plum. Thing is I've already bought a Mini SD card for this phone which won't be compatible with the others and a case, which might be OK but I don't know. I need to go look at these phones but I don't know if I can handle a trip to Chester (my nearest shop)... It's all the more annoying as my neighbour, Linda, has been texting me and I can't read the texts and it won't even call O2 so I have to pay on my landline. AAAARRRRR!!! Does anyone have a view on any of this or am I just wasting my time stressing about it.
