Client to bear cost of discovery's mistake.

Out of nowhere I receive notification that my credit card is being migrated to Discovery Bank. Suddenly for 1 week I have no funds in my card, which I only discover after I receive notification that my debit payment has failed. I now have to bear the brunt of the cost of that failure, because all Discovery Bank can do is apologize for the inconvenience. What utter ******* and disgraceful service. Cancelling my card as soon as possible.
