First of all, you did not clearly state your cash withdrawal time, consumption time, and statement date. These three elements are very important.
If you withdraw cash before the bill date and spend money after the bill date, then the amount stated in your text message is correct. The minimum repayment amount is 60 yuan plus interest (how many days you withdraw cash multiplied by 600 yuan and then multiplied by the king of ten thousand).
The minimum repayment amount next month is one-tenth of 540 yuan plus interest plus 140 yuan, which is about 200 yuan.
Also, remember to explain your situation clearly in the future...
