Received this email, as I didn't deposit any money in Savings account for last 4+ months.
Increase Your ING Savings Maximiser Balance by $100 and Get $50 @ ING
Referrer and referee will each receive $100 for opening new Orange Everyday & Saving Maximiser Accounts ($1k deposit + 5 card transactions/month required). Confirm with the referrer (person you PM) that they have a $100 referral code (ends 31/7/21). Do not participate in the referral system if you do not have a $100 referral code.
