Everytime I see this, I was "in" on the free promos but YMMV.

I had
$30 "2020 Line on Us" from July
$30 "2020 Line on Us 3" from Nov
After recently adding the 4th line on Us, I can see "2020 Line on us 3" on my account, but the discount amount didn't double, upon inspection, it appears the "2020 Line on Us 3" from Nov was gone. Contacted T-Force trying to get it fix, and was told it is going to take 2 billing cycles to get it fix. Check back on my account, all my "2020 Line on Us" promo are now gone, account monthly went up by $60. T-Force assure it will be fixed in 2 billing cycles, should I be worried? Will they be able to fix this type of issue two months from now if the system failed to pickup whatever they promised?

Update: Add via T-Force, using my own sim card. Did not stack anything else with the "2020 Line on Us 4" line.
Update2: Thanks for suggestion of switching Data add on by fellow SDers, but in my case, I'd rather not to touch the One plus promo.

What plan are you on? Did you use your own sim card?
Did you buy any phones with this promotion?

Went to Costco today to add a free line, and was unaware of this $100 rebate they gave me, I was very surprised. Costco reps urged me to go straight home and enter it asap, so I did. Now I'm here reading the comments, that doing this might've void my free line? Or could've has a free A11? What are my options at this point?
Costco free A11 AND $100 shop card was active 12/18-12/24.
You could have gotten a free A11 in addition. The shop card is not the BYOD mentioned in the OP since it combines with a phone. The $200 BYOD deal ended before this round of free lines started. I guess technically it's $100 BYOD since you didn't take the phone, but really. . .
If you qualify, the line is free no matter how/where you opened it. I'd submit the rebate.

Considering all these people who are getting unenrolled messages, I'm very much worried to even consider and get this free line. It might mess up my current promotions. Could you guys take a look at my current promos and give me your advice? Should I go ahead and try to get this free line promo or pass it?

$40 AutoPay Discount
$72 New TMO Insider Voice 20%
$40 2020 3rd Line On Us 2
$40 2020 Essentials Line On Us 3
$40 2020 Line On Us 2
$40 2020 Line on Us 3
$40 2020 3rd Line On Us 3 (Additional Lines)
$16 New TMO Insider Voice 20% (Additional Lines)

I have 12 lines on Magenta Plus and that's why you see $40 discount instead each line.

How come you can get the Essential Line On Us 3? I tried to change my plan from Essential to Magenta, and all reps told me that I would lose it because I would no longer qualify for Essential plan

I never had an Essential plan, I started with magenta plus but I added many lines at the same time that's why they gave me that line I guess. Not sure.
