Reporting of unavailability of the CLOUD SERVICE. In order to ensure the most efficient processing of customer queries, the CUSTOMER - provided that he has concluded a contract with an ATOSS partner for implementation services and hotline services - must submit queries, but in particular those relating to clauses (1) to (4), directly to his ATOSS partner. In such cases, the implementing ATOSS Partner shall in turn contact the SUP- PORT HOTLINE, if necessary. In other cases, the CUSTOMER may continue to contact the SUP- PORT HOTLINE of the COMPANY directly. If the CUSTOMER has concluded the CONTRACT for the CLOUD SERVICE without a SUPPORT HOTLINE, the SUPPORT HOTLINE will only advise and support the CUSTOMER with customer inquiries in accordance with III. Part Number 1. clauses (5)-(9).
