Bill after upgrade
I had a basic phone that cost $40 a month, my billing period was say start 5th of the month.
I upgraded my line to a smartphone and also added a new line on my account with a smart phone, with 3gb shared plan, so my new plan should be around $120. I activated my phone in 25th of the month (10days before my new billing cycle).
So my used my old plan for 20days and new plan for 10 day. So my new bill with prorated should have been...
Old plan = $40/30*20 = 26.66
New plan = $120/30*10= 40
Total cost = 40+26.66 = 66.66
But ATT has charged me $144, When I called them they say its because I prorated in middle of the month I was also billed in advance for my old plan.
I have already called them 3 time to fix my bill, initally they charged me 313, after calling them they corrected it to 246, I was still not sure, called them again they found some issue and corrcetd the amount to $144 but still not satisfied as I am expecting my first bill to be $66.66 with prorated cost for old and new plan, my current last two month bill is $115 (after discounts), which is what I accept but my first bill after upgrade does not make sense and they are not ready to reduce it any more. What can I do, Am I confused or there is something messed up with ATTs billing?
