Help with Atome Card Bill and Payment

Here is my mom’s situation:

First purchase - Oct 18 - ₱950 First billing - Sept bill from Sept 22-Oct 22 paid on Oct 24 due on Nov 2 - ₱2300

May idea ba kayo bat 2300 agad siningil sa kanya?

Next purchase - Oct 26 - ₱1800 Next purchase - Oct 28 - ₱1400 Next billing - Oct bill from Oct 22-Nov 22 due on Dec 2 - ₱4150

Naiinis na sya bat ang laki pa rin ng bill niya. Parang naging total nung tatlong purchases niya eh nagbayad na siya nung una. Ayan na lahat ng ginastos niya. Nagsend na rin kami ng report sa support team nila pero sabi lang icheck if nagsucceed yung 2300 which is oo since nakalagay paid. Pero di namin gets if tama ba mga billing.

Send any input about the situation kasi tom na yung due date ng bill. Thank you!
