McColl's ePOS

My card has been used at various retailers both with chip & pin and with contactless. However my local McColl’s store seems to have problems when I try to use contactless but works fine when I use chip & pin. Not sure if this just a problem with that branch (who recently had their terminals replaced or the firmware updated to allow contactless) or it a problem effecting other branches of that chain too! Anyone else had problems using contactless at McColl’s?
