Business ProfileforIMT Residential

I have lived at IMT Residential (IMT at the Galleria specifically) since February of 2022. I recently renewed my lease with my new lease beginning 05/11/2024 and my old lease ending on 5/10/2024. With the renewal, my reoccurring payments did not transfer for the month of May, therefore, my May pro-rated payment of $506.77 for my previous 12 month lease did not auto draft out on the 1st. I received a notice on 5/10/2024 that my rent was past due and I was charged a 10% late fee. I understand that I owe a late fee for my May rent from my previous lease and am more than willing to pay that. The issue is, I was charged a late fee not only for the amount due for my previous lease, but also for the amount due for my new lease that didnt begin until 05/11/2024. I called to have that adjusted, as the pro-rated amount of $1083.87 for my new lease states in my signed Lease Agreement that it was due until 05/11/2024, therefore, was not late. I have been in contact with my apartment managers as well as corporate to have this fixed to be correct based on my lease agreement and have been denied even though it states in wording that the new lease amount was not due until 5/11/2024. I am wanting my late fee adjusted to have the 10% from of the $1083.87 amount deducted.
