Bad customer service

Ive been standing in yhw que for the over 20mins i wanted to increase my withdrawal limit but they told me it couldnt be done and i needed to go to the tellers when i got to the tellers the lady told me my card was blocked but i hadnt even attempted to enter my pin thus branch at bluff is unprofessional and they are failing to guide us as customers to get the right help , i am still standing in the que coz i had to go back to enquires to sort out this blocked card
