3.3. If Pro+Motion GmbH’s contract partner desires a change in the overall originally agreed service or in individual elements of the service, Pro+Motion GmbH will examine without obligation whether it can implement such a change. If the changes are then implemented, the contract partner must bear the additional costs incurred as a result. Furthermore, the contract partner will owe Pro+Motion GmbH a processing fee of EUR 30.00. This processing fee will arise for each new change request made to and implemented by Pro+Motion GmbH.
