ABC (Agents Balance Care) with Littlewoods

Hi guys, I’ve got my mother’s Littlewoods statements (archive statements) via a SAR and I can see there is a line called “BNPL ABC BAL” which is Buy Now Pay Later Agents Balance Care Balance I.e BNPL=Buy Now Pay Later. ABC=Agents Balance Care BAL=Balance. I’ve looked on some posts on MSE and other sites, and it seems that “Agents Balance Care” was a kind of PPI. In my mother’s case, is BNPL ABC BAL a form of PPI? It varied each month from a few hundred pounds , to £50 odd and then sometimes zero. Any help/advice would be greatly appreciated. Kind regards
