Indeed I've no idea what the arrangements are for this TA and the OP's company. It's quite tricky running consolidators through a corporate market since it's a bit here today, gone tomorrow. So consolidators tend to end up with companies like TravelUp for the most price sensitive, least product loyal end of the market - students and other low spenders. Part of the implied deal is that these low spenders get a chunk of the benefit via a low fare. Whereas corporate travel tends to consider journey management - including picking up the pieces when things go wrong. So a typical private fare would be close to the cheapest price on BA.com but with added benefits such as flexibility with changes, late ticketing, free seating. Then the company would be on hand if there is a cancelled flight and they need to flex the coupon to another service - tricky to do with a consolidation. So while I guess it's possible that the agency is transparent about this with the company concerned, the OP at least was caught out by it.
