BPI gave me 2 cards — gave me 2 customer number.

Please help your first time cc holder girlie out here huhu

So BPI initially offered me a ₱180k cash loan payable for 36 months, but I didn’t push through because the interest was too high. Instead, I asked about getting a credit card.
I went to my branch to update my address since I recently relocated, and I mentioned I was planning to apply for a CC. The staff assisted me and had me fill out a form, then she selected a Platinum card for my application. She told me to wait around 10 days for delivery.

When I got home, I received a message and saw a notification in the app saying I was eligible (no docs needed) with a ₱180k credit limit. I applied through the app, and a customer number was generated. It showed both Amore and Platinum—same as the offer I previously got via call.

After 5 days, I received a Platinum card. Then 2 days later, I got another message that a card was delivered to my condo lobby (I wasn’t there, so I requested redelivery). I initially thought it was just the Amore, but when I checked the app, I saw another Platinum card.

Now I noticed:
I have 2 customer numbers
One has Platinum only
The other has Amore + Platinum (same customer number)
I already called BPI to cancel the Platinum under the Amore account since I only want the Amore (I already have a separate Platinum card anyway).

My question is:
Is it possible that instead of ₱180k, they gave me a total of ₱360k credit limit? Or are these shared limits per customer number?

May bearing ba since nag cancel ako ng card? Will it affect my account?
