Milex Rocket Blender Broke after FIRST USE

I have sent numerous mails to Homemark via the customer feedback site and to info@homemark themselves explaining how my Milex Rocket Blender was 2 months old. I tried it for the first time and the motor cut out after 20 seconds! It refuses to come back on. I complained and Zubaidah from Homemark asked for my address details so that a courier could collect the faulty unit, and exchange it for a working one. Well, that was now a WEEK ago. I have mailed Zubaidah asking when I can expect the courier as I'm tired of waiting with no answer. I have been completely ignored. I sent a follow up email to the customer care page, AND NOTHING! Who knows IF there even is a Courier on his way. I am utterly disgusted in how you treat (or don't is a better word) your customers, who buy your defective products, and when you promise to exchange it, you are nowhere to be heard! What a huge disgrace in non-existent Customer Service, and a massive joke on the quality of your products!!
