Wireless Advocates No Communication, No Rebate Seatle Washington

Went in to costco to get some phones. When we purchased the phones they gave us rebate forms to send in to get gift cards back as a rebate for our purchase.  we sent them in and 3 months late I got my rebate, and my brother got his, but my wife didn't get hers.  when we looked at the Stewart Lee rebate center website it said that my wifes rebate was declined.  Stewart lee would not provide any further information on it and said we had to contact Wireless Advocates for the reason of denial. 

The denial didn't make sense to me since all three of us had purchased the same phones at the same time from the same place and sent in the same forms.  Two of us got rebates and the third didn't.  Over the last three weeks I have sent Wireless Advocates 5 e-mails and left 3 voicemails for them to contact me with information regarding the denial of my wifes rebate and I have not heard back from them.  After contacting them 8 times, there has been nothing but silence from Wireless Advocates.

Obviously they made an error in denying my wife for her rebate and will not speak with me to make it right in any way shape or form.  Avoid any business with this company at all costs.  if a mistake is made it WILL NOT BE MADE RIGHT!!!
