One of your sales woman broke my trust.

You will get the $110 upfront and the difference in bill credits over 24 months.  You won't see everything until a billing cycle or two.  It's been this way for a long while now.

T-Mobile is rumored to change how this work because of responses like this as most don't understand how the promotions work.  Now on the next billing cycle for 24 months you'll now just get the full credit vs $110 initial and the rest over 24 months to make it easier to read.
