Unless you are abroad or the time is late in Switzerland, it is usually better to call us at +41 (0)78 626 54 33.
Indeed, with email, because of the anti-spam filters, both your question and our answer may not reach their recipient. In addition, it is often more effective to talk to each other directly.
Information to provide in case of contact by email :
1. First name, last name 2. Company or organization (if applicable) 3. A phone number to which we can reach you (including the county code if you are outside Switzerland) 4. In case of no answer when we call you back, should we leave a message on your answering machine or not.
