There are NO words for my disgust!!!

So basically. I upgraded Beginning of this year to a Nokia 1320. BIGGEST MISTAKE!!! Phone has been in 3 times for repairs. Each time I must wait 21 days to get my phone back. This time though takes the cake. The phone comes back from your head office without its back cover. I get told my the branch, that it will another 48 hrs. I go to fetch my phone [48 hours later] today and I get told I must now wait until Friday because your head office hasn't sent the cover. I naturally get upset and tell the consultant that I don't care if he opens a new box, but I want the phone today. He proceeds to tell me the phone has been discontinued so he cant do that. DISCONTINUED, gee I wonder why.... I'm at a loss for words. I actually dont even want the phone anymore, because I can guarentee you that in a month or 2, I'm gong to have yet another problem and be phoneless again! So what must I do, maybe go to the ombusman for poor service delivery. Oh and guess what you cant phone me. I STILL DONT HAVE A PHONE
