Usually an e-mail is sufficient unless issue requires urgency. We would want to dial # 800-895-7412. This use to use Sennheisers main support number and it kind of still is but the company that took over is called “EPOS”. They will still be able to help us out with any headset needs.
We should be e-mailing email@example.com
As we are waiting for a reply we want to schedule a callback for the Customer 1 day out. If Sennheiser has not replied by the time we need to callback we still want to call the Customer and keep them in the loop of what is happening.
We also want to keep the ticket updated with the notes from Sennheiser.
