Upgrade NIGHTMARE!!!

Beyond furious with this company. First BIS cancelled 2 weeks before 24-month period lapsed. Followed by the phone I chose as an upgrade is discontinued, not discontinued, discontinued... etc. You get my point. THEN, my upgrade package is never migrated to the SMART S package which I requested when I did the initial upgrade but airtime is loaded to my account as per my old contract. I have waited about 3 weeks for my handset (which is on backorder) and will be receiving this next week without any data available on my contract. Spent 45min now on hold for upgrades department only to find out I was not put through to the right department. Was then told she will be putting me through to upgrades and then CUT OFF. Frustrated to the max! Then, chatted to online consultant about my frustration and was given the number for cancellations. So here goes, my last attempt at making this contract work. If my account is not switched to SMART S before I receive my handset next week, this contract is history! I seem rude, this is not my normal nature but I am limited to text to describe to you every call and incident which occurred since the start of this nightmare. Over it.
