Received a voucher code, but can't use this
I like to order a new auto navigation and tried to buy it online. I received a voucher code valid until 9/2/21for 10%, but it is not accepted.
I can not find any email address for support, so I can not disclose the mail addresses that I used in the forum, so please give me a method to provide this info.
Mod edit: Please don't post private or personal information on a public forum. Thanks!
