Can tenant reverse their rent?

[Faisal Zaman]

Unfortunately one of my tenants defaulted in March'24. She paid rent till February using one of the rent collection platform that I have been using. Last week she recalled the February month rent saying that she didn't authorized the February rent.. Now the platform returned her the rent and asked me for withdrawal of paid rent in February. Based on IL law tenant cannot ask for rent refund.

Question, shouldn't the platform work with the tenant with to void the wrong claim since the platform has lease and all the transaction information that's the payment for February rent? Based on this recent experience, I have lost all the faith on these types of rent collections platforms.. 

Any thoughts how to avoid these types of situation like reverse rental payment?
