I was previously bundled and recently changed my phone services for a lower priced bundle. I had already received my $10 DirecTV credit under the old plan and within a day or so automatically received the new $5 credit under the new plan. I'm saving way more on the phone bill than I lose with the reduced DirecTV credit.
But, it did take almost 90 days for the original credit to appear way back when I first applied online (I did get a confirmation email that I saved though) and I had to call to get them to get it right (they did a 3-way with BellSouth, DirecTV and me), but I did get the back credits.
I've had a similar experience so far. I too was a current bundled subscriber and switched to a new cheaper bundle online. Like you, I still get my old $10 credit plus the new $5 credit. However, my phone service is still unchanged after 2 weeks of "processing", so no phone bill savings for me yet.
UPDATE: Finally got it straightened out after a couple of emails. There was a line item in my order showing "GF DIRECTV" cancelled. I assume my GrandFathered bundle discount will go away, to be replaced with the new one. Keeping my fingers crossed that this part of the order falls through the cracks since the directv part of my discount was greater before ;-)
