Why not? It is a softcapped account btw. They cannot charge you for Blended usage above your cap.
My account is hard-capped at 5GB, but my ISP does not cut me off. They also allow me to reconnect after 24h even if I am "capped". I don't pay anything extra and I am supposed to be cut off after 24h/5GB but neither, so I am quite content with what I get.
