Pro Rated rent @ closing

[Justin Reader]

Today I had closed on a duplex, signed all the necessary papers and after I had left I realized that I had not received the rent checks or the security deposit from the seller. I had called my agent, he reached out to the sellers agent both seller and sellers agent said " its only 5 days rent you should have said something @ closing were not worried about it"...  seller also said he had given the tenets back their deposits...would anyone have any advice for me? 

I am not going to go broke on the $200 for the rent that's owed to me for those days.. Its mainly the principle that they are acting the way they are.
