POOR SERVICE DELIVERY FROM MAKRO AND DEFY

Dear Makro and Defy Recently purchased a Defy Hobb Set touch top from Makro Strubens Valley on the 10th of August 2010. After instalation within the week of purchase it was identified that one of the touch senses on one of the plates is sticky and requires alot of pressure to put that specific plate on. I called the call center who advised me to call the makro salesperson as it was a matter of 4 days. I was advised by the salesperson to bring the stove top back to the store. I returned with the stove top on the 15th of August to the store customer service department. I was advised to take it back home as they would log a trouble ticket with defy to get a technician to me on Monday the 17th august. However to date I am still awaiting a technician. I followed up on many occasions with the call center and each agent in the call center promises me a callback and nothing to date. It's been 16days since I purchased this item. Terrible service from Makro. It has been over 14 working days since I purchased this item and its absolutely frausting with the service that Makro is actually not providing any assistance with this issue.
