The Tranquil Lodge Group refused to address issue

I want to acknowledge that The Tranquil Lodge Group has attempted to resolve this issue. However, the solution they're offering (a $18.25 store credit) isn't adequate considering I paid $18.25 for a jacket that never worked properly.

Dear customer, I am reaching out regarding your recent complaint about our extended warranty. First and foremost, I want to extend my sincere apologies for the frustration this situation has caused you. As the Customer Advocacy Manager at The Tranquil Lodge Group, I have personally reviewed your case and have spoken with the team members involved.

Processed a refund of $450.77 to your original payment method 2. Added a $450.77 service credit to your account for future use 3.
