Dimwitted dormancy lock

First Discovery forces its long-suffering clients to get a bank account in order to access our travel benefits, which I duly did in November. Today, I transfer money into the account so that I can pay for a flight. But when I try to pay for my flight, the card is declined! After numerous attempts, I call the help center (around 8pm), and I get told that there is a "dormancy lock" on my card due to lack of use, and I possibly have to wait until tomorrow for someone to unlock my card! Funny that Discovery had no problem taking my money, then have a problem when I try to spend it! What a farce.
