The surcharges imposed by this part shall be collected insofar as practicable at the same time as, and along with, the charges made in accordance with regular billing practice of the service supplier.
The charges for services determined by or stated on a billing of a service supplier in accordance with its business practices and accounting records to have been supplied to a service user during any calendar month or billing period of the service supplier shall be presumed to be correct. The presumption may be rebutted by evidence which establishes that the charges for services were other than such amount.
