Discovery Comunication

I would like to know why is it so difficult to send an email to someone at Discovery.I have been on the phone for 20 min spoke to 4 consultants eventually the phone went dead. The omline or whattsapp lines are useless So all I was requesting was a contact email adress the two which is on line '***' *** tell you no longer in use if this is so then why not remove it.As stated the online chat is a waste of time
