>>9312931>>9313002Ask them if they will cover the cost of the third party replacement elbow joints for Decade (it's not that much, something like ~$10 + shipping). That seems reasonable enough, and still allows them to keep most of the money.
If they continue to ignore you even after that though, file a chargeback via PayPal and follow up with evidence/sending the figure back if necessary. Then just buy the reissue.
