Voucher not received

[sacschumac]

I had made a purchase 70 days ago using the voucher code. I have received the item i purchased but haven't received the item associated with the voucher (the item ebay is supposed to send me). They asked me to wait for 60 days but even three emails to the customer center and unlimited tries at contacting them on their toll free number, I haven't received the free product. This is irresponsible behaviour and I haven't even received replies to the emails I have sent them. Please help!!
