Service Hotline

Support contact via Service Hotline


Definition "Service Hotline"

Customer service departments of companies can be reached by telephone for a variety of issues, such as technical support, order acceptance, complaints or even simple enquiries. To optimise the accessibility of a service hotline, service numbers such as 0800, 0180, 0137 or 0900 are often used. Such service hotlines can then be reached nationwide under the same number.
