I was asked by Terence Mthembu, Service Advisor-Call Centre, from Defy, to rate his service. Well, unfortunately not good! He responded initially on a warranty request via email (it wasn't very easy to log a warranty call in the first place). After requesting the address, he said he would respond in 72 hours. It is now 3 weeks with no response.
