7. If a data intermediation services provider has its main establishment or its legal representative in a Member State but provides services in other Member States, the competent authority for data intermediation services of the Member State of the main establishment or where the legal representative is located and the competent authorities for data intermediation services of those other Member States shall cooperate and assist each other. Such assistance and cooperation may cover information exchanges between the competent authorities for data intermediation services concerned for the purposes of their tasks under this Regulation and reasoned requests to take the measures referred to in this Article.
Where a competent authority for data intermediation services in one Member State requests assistance from a competent authority for data intermediation services in another Member State, it shall submit a reasoned request. The competent authority for data intermediation services shall, upon such a request, provide a response without delay and within a timeframe proportionate to the urgency of the request.
Any information exchanged in the context of assistance requested and provided under this paragraph shall be used only in respect of the matter for which it was requested.
