Tenant Late Fees Delayed

[Rashad A.]

Hi, 

I have a situation here and wanted to get you all feedback. My tenants have been delaying monthly fees for sometime now. In particular they were late in November and December for few days. Now, they have paid monthly rental fees but not the late fees. Tenants are aware of amount for late fees, and were supposed to pay them this Friday. They have told me earlier this week. I texted tenants today to follow up no answer. What would you recommend I should do next?

Thanks
