change of PIN

so I call in today as apparently, I entered my pin incorrectly 3 times? Incredible helpful consultant says it has been reset and I need to follow the instructions in the email I receive. 6 hours later I receive the email and follow the steps outlined. the message I get is that the card is not in a valid status. I call the call centre and am told that I need to wait 24 hours before I try to get a new pin. This is NOT what was explained. -GO LISTEN_. I ask to log a complaint... and wait for it....I am told I cannot but MUST CALL IN AGAIN... ***. almost 8 minutes on the phone. why ot just send me the mail in 24 hours. ****py tech people that Discovery employ...
