Sent $52 interest for this month. the lacking amount be paid on next week.
Your loan repayment due was 262.5. You sent 52$. The new repayment amount should be 212.5$ after the extension, the new repayment amount will be 318.75$. So, within 7 days, you must have to repay at least (318.75-262.5)= 56.25$ to avoid any unwanted incident.
My payment should be $87.5 for this month interest 50%. I give $52, so im lacking $35.5 - I have transferred it now. So im complete with the interest for this month.
