It's from a shop inside amazon, i don't know how trusty he is.
I'm gonna talk with the vendor and see what we can do but i'm not optimistic about it...
Hey, if there is a genuine problem or flaw with the porduct, ESPECIALLY a safety concern, then you are fully and rightly entitled to a full refund or replacement.
No other course of action would be fair, just, right, sufficient etc.
It is your absolute paramount right. Dont just roll over. They owe you.
Contact them. Be polite, sincere, but insistent. Simply insist that they make it right.
If they dont cooperate- open a Dispute with Amazon. Dead easy- just explain the issue, they prob want a photo, and I guarantee you they will refund you and mediate with the seller.
In this day and age, this is how things are. They sent you a bad item. They are wrong and have an obligation to make it right. Your perfect entitilement, anything less is unacceptable. Seriously. Good luck but have comfidence and please keep us posted.
