Quota exceeded

I am trying to list a property but it says quota exceeded but i have 4 available i just listed 1 add and now i want to list another commercial property but it says cross-city listing limit reached ?
How can this be as i have limit of 5 i used only 1
Kindly resolve the issue

Dear M.A. Rauf,

Only residential property can be posted under the free listing option. You cannot post commercial property under the free listings.
