I ordered a wireless earbud adapter from the KZ Official Store (seems pretty trustworthy, one of the largest tech suppliers on the app with a ridiculously large amount of positive reviews) the KZ store forgot to write my home address on the package they sent, so after waiting nearly 3 weeks for the adapter to be shipped to the UK, the company that was meant to deliver had no legal choice but to cancel the delivery and send the package back to supplier. No refund or replacement has happened yet
