Unprofessional conduct towards clients

I requested some assistance from kwikot regarding a geyser installation. The marketing manager, Lionel Schultz, was helpful, but did not have the technical knowledge. He referred the query to the technical director, Herman Weber, who just did not bother to reply. After 2 requests by e-mail I am still waiting for a response from him. You have a moral responsibility towards your clients to at least, reply to their e-mail, if you are not capable to answer their queries.
