Hello Goojoomoo81
My dear colleague @Danhiel is right.
The free day pass for GA holders for a companion is only available if you had given consent to receive personal offers. The Swiss data protection law does forbid the sending of personal offers when the customer did not agree to it.
However, there is no entitlement to the free day pass; it is a thank-you gift and not part of the contract.
Kind regards,
Roland
