Quality issues with Grand Oasis International product

I want to acknowledge that Grand Oasis International has attempted to resolve this issue. However, the solution they're offering (a $414.92 store credit) isn't adequate considering I paid $414.92 for a fitness tracker that never worked properly.

Dear customer, I am reaching out regarding your recent complaint about our premium membership. First and foremost, I want to extend my sincere apologies for the frustration this situation has caused you. As the Resolution Specialist at Grand Oasis International, I have personally reviewed your case and have spoken with the team members involved. There appears to have been a miscommunication regarding our service guarantees, and I take full responsibility for this oversight. I have taken the following immediate actions: 1. Processed a refund of $38.46 to your original payment method 2. Added a $38.46 service credit to your account for future use 3. Implemented additional training for our staff based on your feedback Your case has been assigned reference number REF-AA49AF10 for any future correspondence. Please allow 3-5 business days for the refund to appear in your account. Thank you for giving us the opportunity to address this matter. Your feedback helps us improve. Sincerely, Rowan Hall Resolution Specialist Grand Oasis International
