I applied for a CCB credit card, and they approved three, so are all three the same, that is, 5000 each, three 15000?
If you apply for one, how can I give you three? Did you fill out three application forms without knowing it?
Your credit card limit under the name of CCB is shared, not accumulated. In other words, your three credit cards with a limit of 5000 can only add up to 5000, not 15000.
