This error "Unable to find axis service for service name" is a known issue[1] when a data service is invoked as a Rest service with query parameters in MI-1.2.0 and this is already fixed in MI-1.2.0 with the latest updates. If you have a valid wso2 subscription you can get the latest updates using the Update 2.0 tool[2].
However, you can invoke the data service in soap manner or rest manner without query parameters and check the mediation.
