No me gusta Babies R Us

Ugh!  I'm SO frustrated with Babies R Us.  Right before I got pregnant with The Princess, a Babies R Us opened up about a mile from us.  I thought it would be heaven.  I was WRONG!  When I first went to register there my SIL who was 6 months ahead of me with baby #1 cautioned me that their customer service could be difficult.  Well it wasn't my only registry but I was excited and did it anyway.  It took FOREVER just to get someone to show up at the registry desk to get us started.  That was my first experience there.  Then every time I've gone into the store, out of the 10 check stands that they have, none are open and you must go to the customer service desk.  So you end up in a line with everyone else who is returning, etc.  Pain in the booty!  So my last straw came last week.  After The Princess's 4 month Dr. appt. we needed to get her some liquid vitamin D.  We still have credit to Babies R Us and I had a coupon (don't even get me STARTED on all of the exclusions on their coupons but it does sort of play into this story) so we went there.  I had read every exclusion on the coupon to be sure that our vitamins would be covered.  No exclusion on vitamins.  Perfect.  Not so much.  When I went to checkout, (at the customer service desk of course) the girl couldn't get the coupon to work.  Mind you-it's from THEIR store on one of THEIR receipts.  She finally calls someone.  Together they determine that since the vitamins are made by a formula company that they are considered formula.  Uh...no.  They are not.  Just because my washing machine is made by GE it is not also a refrigerator.  So I came home and contacted their customer service.  They emailed me back wanting the store number and I got a canned email back.  No attempt to try to rectify the situation, just a "Thanks for your email. Sorry it happened." email.  I felt that they should have at least offered to honor my coupon and send me the couple bucks it would've saved me, even if it was store credit.  Am I out of line on this one?  Are all Babies R Us stores like this because I haven't heard much in the way of "good" regarding them?  Thankfully between SuperTarget across the street and Amazon.com I can get The Princess's items elsewhere as soon as I use up our credit.  I'd like to hear what others think.

Here's the email from customer service if you're interested:
