Poor Quality Item Complaint Receives Zero Response

Running up to a recent overseas holiday I purchased a Deuter Spider 25 backpack from Cape Union Mart Canal Walk, within two days of the trip one of the primary zips had given out, something you're obviously hoping to avoid by spending the extra amount on the brand name (R900). The backpack was still functional given that compartment still had another zip, except that within weeks of returning and while out the country on business this zip too gave out to the point where I now have an essentially new but entirely useless backpack. Having lost the slip, I emailed [Email Removed] (23rd November 2015) and received zero response. After a week I then contacted Cape Union Mart via Facebook and the response was immediate, the guys apologised and sent me an alternative email address they were sure would be of help: [Email Removed] (emailed 30th November 2015), and to date, December 5th I'm still awaiting a response. Guys, get it together, you've got a good brand but you're dropping the ball here, customer response is where you win or lose your marketing spend and the only reason I'm here is because you couldn't get back to me...
