Overcharged by Projects Group for service

I want to acknowledge that Projects Group has attempted to resolve this issue. However, the solution they're offering (a $443.75 store credit) isn't adequate considering I paid $443.75 for a fitness tracker that never worked properly.

Dear customer, On behalf of Projects Group, I would like to personally apologize for the inconvenience you've experienced with our premium account. We strive to provide exceptional service to all our customers, and we regret that we fell short of this standard in your case. After carefully reviewing your complaint, I have authorized an immediate complementary accessory package to address this situation. Additionally, we have documented this case (Reference: REF-DED69340) to help improve our training and service protocols. Please feel free to contact me directly at extension 4567 if you have any further questions or concerns. Yours sincerely, James Thomas Customer Satisfaction Coordinator Projects Group
