Has anyone been able to get bill corrections caused by DECEPTIVE DISCOUNT OFFERS?

 Its in published offers online.  And they all do it.  Verizon has a $10 discount also.  
The published prices INCLUDE the discount.  Without it its $70 per line for 2 lines.

Online tool

Your base plan should be 120 for 2 lines.

Thanks for the reply.  I'm not at all sure I used this same tool when I built my order.  There was a Special Offer for the iPhone XS that started my research.  I see on this page the fine print at the top of the page, but, not noted at all in the highlighted boxes with bolder type.  I do know that it did not appear in my shopping cart when I built my order (have a screen print).  As I mentioned in my on-line chat with AT&T, it was at best deceptive or well hidden and at worst ...

Since the cost in the tool is the same as your quote, $60 per line for 2 lines, the tool worked correctly.  
The only prices honored are the ones that are published online, which are correct, and which agree with the quote that you mention in your first post.  

I went through a “purchase” as new sign up.  

If you click on ‘no thanks’

Again my path for this purchase ran from a special offer on the phones, to the Cart, to the purchase process.  When I was in the purchase process, the "base" price was $60/line.  I did ask in an ongoing on-line chat during the purchase whether or not Auto-pay provided a discount, so I clearly hadn't seen the page you printed above because it clearly states there is a $20 discount. Based on this view, I would have expected$20 off what I saw as the "base".  Had no reason to hit "No Thanks" or choose not to take the 'additional' discount.

I do appreciate you trying to make this make sense to me.

BTW, How do you interpret the section above that says "AutuPay and paperless billing" and "Remember to sign up for both to save $40 each month"???

This sounds like $40 off $140 ($70 X 2) or net $100  Exactly, what I was expecting.

Again, I think AT&T makes a concerted effort to bury important information and present a confusing (at best) offer.

Thanks again for your effort and interest.

I'm beginning to feel the best I can do to feel any satisfaction with this transaction, is to spend the next 30 months freely sharing my opinion of AT&T with anyone I encounter who might be interested.  I might not get the money I feel I deserve, but perhaps it will cost them 5 -10 times the cost of doing the right thing.

Dont know why $40 would show for 2 lines unless you select Elite plan with a Fan discount (I have one, but went for sign up as new customer).    Glitch maybe? 

All anyone will tell you is the online price tool is correct. 

I played around that I was able to reproduce the $40 error by editing my cart and removing a phone and changing the plan and then adding a different phone. However my cart still shows only two lines.   Prices are inaccurate as well.

   Somehow it does not know how to do basic math. I have made a post to the community manager that they need to take a look at this

Thanks again for your efforts.

I felt like 'customer service' was treating me like I was stupid or crazy.  As you mentioned, they will just keep telling you the bill is correct regardless of what you were shown on the website offer.  I guess they think they are infallible, or if not, you just have to live with their mistakes or misrepresentations.  Who knows?  At least now, I better understand the pointed jokes about AT&T service.

And customer service is correct, your bill is correct and there will be no change other than AT&T correcting a bug in their ordering system. The published prices are correct and those are the only prices AT&T will honor.

The most you will get is a thanks on this thread for bringing a bug in the system to their attention.

A $10 credit per line which reduces your monthly charge from $70 per line to $60 per line should appear on your bill
