It out-sources the billing service to an external agency. An un-proper item pops out monthly and over-charge me $75. I visited the rental office times and at the end I just wrote to them. They did nothing. At the same time I wrote to the billing agency and it took it from form the statement.
The rental office still keep bugging for the balance(I paid all but the un-proper item). An lawsuit is on the way.
They overcharge my friends also and it has list of fees which you barely can understand.
