Worst service

Discovey just provided me with the worst possible service you can imagine - trying to change an incorrect cell phone number, turned out to be an half an hour process with zero luck! and now the lines have technical difficulties. For OTP changes one needs to phone the credit card division - ***, due some technical issue, the call goes to CARD COLLECTIONS - who in turn transfers you to a dead line! 5 consultants later, now i must send an email apparently - Discovery is obviously making to much money
