Towsure discount

so ive been to towsure sheffield this morning went to the counter to pay and showed my cc membership card expecting to receve my 5% discount for being in the cc to be told that towsure now dont give the discount anymore i carnt belive that the club and towsure have parted company and now you dont get the discount i use towsure a lot and the 5% isnt a lot but its there needless to say im rather dissapointed
