So, for anyone struggling, I, too, was unsuccessful multiple times when trying to submit a review for my free starter kit.
I found the review page buggy, but by following my instructions, I guarantee you will be able to submit yours. Some people received the email earlier than expected, but expect it 14 days after the delivery date if you haven't.
- First, don't use any punctuation in your review title and summary except for fullstops.
- Second, keep your review and title short. I don't know what the character limit is, but I had to shorten mine and was able to submit, as you can see in the screenshot below.
- Finally, some of you may have issues with your name not being accepted; in that case, you have to come up with something unique by adding numbers or letters as needed.
Just a reminder: the Starter Kit terms are as follows:
"We will email you a link to complete a review form after the 14- day returns period has expired. You must review your phone using that link within 30 days of receiving your new handset, using the same email address you used to place your order. You will not receive a confirmation email once you have submitted your review. Once your review has been validated, we will deliver your free gift within another 30 days"
These are links to submit your review.
I hope this helps, as I hate missing a deal. I can make someone's day by helping you get the free goodies.
Let me know in the comments below if my post was helpful.
