Staples Rebate never issued Davie, FL Nationwide

On June 7, 2015 I purchased a shredder from Staples in Davie, FL.  The reason I purchased the unit i did, is b/c in big bold letters the sign indicated $25.00 rebate.  The rebate was to be in the form of a $25.00 VISA card.

When I submitted my rebate, online, I was told that my rebate would be delivered to me within 15 days.  It is now August 2, 2015, clearly much more than 15 days - almost 60 days and still no rebate. 

In the 2 communicaes I've had w/Staples, July 9 and July 30, again I was told it would be 15 days and my VISA will be delivered.  

I've lost complete faith and trust in Staples.  Whenever I am in need of office supplies, it will be Office Depot that I will frequent.
