Frustrated for incorrect billing again

This is the fourth time I have made a complaint regarding my account. I have been up to date with my account, and since I upgraded *^&*^ has hit the fan! I sent numerous emails and called in and still no solution. Taking time out of my day to make these unnecessary calls. I was told that I was incorrectly billed for a free phone with my new contract, and it will take 7-14 days to be investigated and reimbursed. I get calls 20 times a day from a voice prompt stating that my account is in arrears and if i do not pay my line will be cut off.

I also do not have caller identity because of this arrears $^$%^ which is very crucial to have right now!

To make things worse, my "Bill so far" has increased even more since I last made a complaint. Not only was I billed for the free phone, but also "My 10 Gig promo" TWICE!!!, x2 handset installments??? Thought the upgrades kick in with an early upgrade? What is the point of having a choice to have an early upgrade if I have to pay for 2 handsets!! To make it worse I am now billed for x2 SMART Line rentals.

I am beyond frustrated and I want to return these #$%&^$ phones. !!

PS. P**^^sd off client.
