Charge 5 cannot use coupon code

[QuadsOrBlades]

Recently my Charge 5's screen suddenly went black after about 2 years since purchased.  I tried all of the remedies found in this Help section, but nothing worked.  I actually got through to customer support, and they generously offered a discount on a new Charge!  They emailed me a code with instructions, which I immediately tried to use to buy a new Charge 6.  After I entered the Promo Code the site stated, "Coupon code has met redemption limit".  I emailed customer support, and they replied that it takes 24 hours before the code can be used (says nothing about this in the email they set with the code).  I waited until 24 hours had passed, and received the same message on the Checkout page.  Mind you, I copy & paste the code into the Promo Code box, so its not a typo (I even make sure there is no trailing space).  I let customer services know, and this time I get absolutely no response.  It has been more than 4 days since anyone has replied. 

Am I being ghosted by FitBit/Google? 

What is reasonable waiting period?

Moderator edit: clarified subject.

A warm welcome to the forums @QuadsOrBlades. 

Thank you for taking the time to share all this information regarding your Charge 5 and the details about the contact that you had with Support.

I reviewed your information, went ahead and send your inquiry to the Support team for further assistance with this. In this case, they will let you know how to proceed. Please keep in contact with them and take a look at your inbox.

Why would you pay for another item from a brand whose watch died after 2 years of usage? An issue reported by thousands of customers. Don't give them your money.

For a couple of reasons:

1. For 50% off its worth giving them a second chance, as it makes it about as inexpensive as a competing product.

2. My previous Charge lasted much longer, so they can do it.  I am hopeful the Charge 6 has a longer life.  If not, then I will switch.
