If you browse to the "customer service" page of the bs.store at
http://bsplayer.com/en/bs.store/home/customer_service
you get the following text:
BS.Player Store is owned and operated by WEBTEH Ldt.
If you incur any problems or have any questions concerning merchandise
or the status of your order, do not hesutate and contact us.
The "contact us" is underlined and contains a link,
presumably an email link or a web form.
But by clicking it, NOTHING HAPPENS.
I think this pretty summarises my experience
with the bs support service.
I have also tried emailing to customer.support@bs...
and responding to the purchase confirmation email i got... but to no avail.
