First, call the restaurant where you put the order. You can call the store or get in touch with them through the Subway app or on your ticket.
Kindly describe the problem, including what was bought, when it was delivered, and how it was.
If you let them know right away, many places will give you a new or refund right away.
If the shop doesn't answer or if you placed your order through the Subway website or app, go to subway.com/contactus and fill out the Customer Care form.
Include the date, location, order number, a full description of the problem, and pictures if you can.
This helps Subway take your issue to the next level and figure out how to compensate you properly.
If the problem remains unresolved, consider filing a complaint on Xolvie to raise awareness about the issue and inform others.
