citi checking bonus可能拿不到了，有无挽救办法？

九月初开了citi checking，准备薅存30k拿500的bonus，结果想着钱太早进去也没有利息，于是十月初才转进去30k。昨天打开看的时候balance变成29985了，扣的是九月份的月费，今天跟客服要回来了但是offer details页面变成了这样，感觉bonus应该是拿不到了，想问问是应该当机立断转走30k赚利息，还是等到十一月月底，拿不到bonus的话再找客服撕逼？

edit: 详细读了一下terms应该是拿不到了，还是打算转走

Maintain your Balance. So long as you maintain at least a $30,000 Balance every day for 45 calendar days starting on the 46th day after you open your Checking Account, (“Maintenance Period”), you will remain eligible for a Bonus. Your Balance must be held in your new, eligible Checking Account. Please understand if your Balance falls into a lower Balance Level for even one day during the Maintenance Period, your Maximum Bonus will change (see Chart). For example, if your Balance on the 45th Day is $200,000, the Maximum Bonus you could earn is $1,500. If your Balance is $150,000 on day 50, however, the Maximum Bonus you can earn changes to $750.
