Bad after sales service by Devy Headoffice and branch

I am a loyal Devy appliance user- however with my Devy Autodry Tumbledryer I have had extremely bad service from DEVY APPLIANCES -tel ********** as well as the Midrand brance where the parts is supposed to be delivered to tel 011 ********** . In FEBRUARY this year, yes FEBRUARY I ordered a part for my Metalic Silver tumbledryer JOB Number is ********** - about 2 weeks after my order, the Devy technician came to fit the part-it was the wrong color(white) he then went back to Midrand and ordered the metalic silver part- that was in Feb, and every time I call, they promise to call me back. One day I called the Midrand branch and asked the guy to check the job no and what is going on there, why is NOBODY calling me with an update, you know what they guy said.....they do not call because they have NOTHING TO REPORT ON!!!!!! What an answer to give to a loyal customer,who has been waiting for 3 months to get a stupid part. Worst SERVICE ever , is the part not available and coming from overseas or WHAT is the problem ??????? I called the head office again this week on Thursday , gave the job no and asked what she can tell me......according to her they ordered a new part last wee**** What???? 3 months after I ordered it? Then she said that the correct part did arrive but it was "damaged" . Did anybody bother to call me and tell me that the part was damaged and they ordered another? NO NO NO .....I am so disgusted with DEVY is is unreal. Unfortunately I have a washing machine, fridge, stove -all DEVY and if any of those break......I cannot imagine......I hope the big boss of DEVY will get this complaint and ACT- this is absolutely not on, I should have bought Samsung instead........please anybody with authority at the head office and the Midrand branch-take charge and get my part and REPORT BACK. This is unexceptable service.....worst ever!
