You have a legitimate complaint with her... she should never have committed to do that and then ignore you. However, in light of the fact of ever-growing unemployment and what it will do to our society, I suggest that you take it up first with her (in the store), but if she balks, only then go to the manager. Let her know upfront that you will complain to the manager, and I bet that will do the trick. Frankly, I wouldn't want to be the one responsible for someone's losing his/her job - especially with children involved - even if they had shafted me, and I'll bet you wouldn't, either. We are in for some bad times.. times that call for overlooking a lot of petty problems. But this is a good lesson for all of us... as the Germans say, Selbst getan ist wohl getan... more pithilly, if you want a job done right, do it yourself.
