The Word "No" does not exist for Discovery

Discovery does not take NO for an answer, they do not understand these words either "STOP PHONING ME" either. The last time they phoned they told me to go onto their website and unsubscribe from their calls etc., i did that (I DID NOT OPT IN FOR ANY COMMUNICATION TO START WITH) and to this day, Guaranteed they are phoning, PLEASE STOP PHONING ME!!!!!!!!!!!!!!!!!
