Discount offered, but still not getting it a full billing cycle later.

WTH!? Verizon!! I get an unsolicited text offering "loyalty" discount. I was planning on calling anyway to "try" to get the $230+ billdown on the 2 lines. I called last month was supposed to get discount of $10 for each line and though it sucks that there is really no getting bill lowered because I use all the perks, etc of our existing plan. I at least felt a bit better for the 12 months discount and appreciated the honesty of the agent and her not trying to constantly upsell me the entire call.(I wish tech support were as great about THAT!,) BUT, I get my bill yesterday and no discounts..AND NOW I'm getting a new text with only a $10 on select lines on same day for only 6months?!
