Miss Rosie has a lavish spending habit, particularly using her credit card (CIMB Platinum Visa Credit Card). She prefers to pay only the minimum amount each time the statement arrives. On 1st October 2021, her outstanding balance was already a whopping RM18,500. However, that did not deter her from controlling her shopaholic behaviour. On 4th October, she had bought through online purchase, a handbag costing RM850, a sunglass costing RM630 and a designer skirt at RM480. On 6th October, she had purchased the latest smartphone at the Samsung store and this costs RM7,000. Since it was a big amount, the store, collaborated with CIMB Platinum Visa offered customers who made a large purchase to turn into smaller payments with an instalment payment scheme. Miss Rosie thus agreed to this instalment payment of 12 months and the first instalment was effective on the date of purchase. Other transactions that Miss Rosie paid for using her credit card were
