False ***** alert- locked card

If I could give them a zero rating I would. A transaction made to my account was raised as a red flag. As the transaction was made by an FNB account, I had notified the person who made the transaction who then proceeded to remedy the situation with FNB. My card was locked without my notification and I was stuck at the petrol station with a locked card. I have phoned Discovery Bank numerous times speaking to their ***** department who time and time again refused to take some sort of initiative and contact FNB to remedy the situation. On two occasions I was left in tears at the absolute disregard and almost accusing nature of the consultant on the other end of the line. It is now month end and my salary will be paid into my account with me having no access to it. Discovery has truly disappointed me in this regard.
