Hello Shoapaugoagh56
Not all options are listed there because the Companion ticket is primarily an offer destined for residents, yet tourists are not excluded, although not all Swiss Travel Pass products are mentioned.
If you want to stop your refund request, you have to call SBB (if you purchased it from SBB): +41 51 225 78 56 (24/7, waiting times may occur).
No, the coupon cannot be used to purchase a Swiss Travel Pass. The coupon is only valid to purchase a resident’s Half Fare Card.
Kind regards,
Roland
