City Union Bank — Server down

This is very worst every night cub server goes down i don’t understand why ! Why cant you keep your servers as 24/7 is it so tough to keep 24/7 huh . Each and every customer of your bank will be unhappy . Even in night time while i need to go out station my card wont work is this way you treat your customers. Resolve this issue or else i would have to move other bank
