Don't know who the "they" you spoke to was, but if the shop was successfully submitted, someone has a record of it! If you've only spoken to one person so far, I'd take it further. Sometimes one hand doesn't know what the other person is doing. For example, if "they" were in accounting, perhaps someone did not funnel the "to be paid" information. That actually happened to me once with a different company, and the problem was ultimately resolved.
