Discovery and Uber in the dogbox

Discovery Bank and Uber seems to have a nice never reply to emails review going between them. Uber created a system tp sign on for a monthly discount that did not want but I pushed the wrong button. Since then I have been trying to get them to reverse it. They don't reply to emails. So I then tried to get Discovery Bank to reverse the entry. They don't reply to email or tell you that the email is no longer functioning. Phoning them is quite useless they never come back and use people that are not properly trained. If one uses the BOT it only asks simple questions. Dealing with Discovery bank is becoming increasingly more difficult. Discovery also provided an email address for Uber which simply does not work.
