Defy - poor poor after sales service.

I wrote to "Hellopeter" about 2 weeks ago but got no satisfaction. I will repost my letter and hope something will come of it. "MEMO 2 May 2018 I bought this gas oven/stove and had no hassles with it. I contacted Busisiwe Moshokwa via email and she had a technician coming out to have a look. The oven gas regulator is faulty and need to be replaced, but according the technician, they are almost obsolete. Am I to believe that Defy do not carry spare parts and that after every 4 to 5 years have to buy a new gas stove/oven to the value of about R 7000? If this is the case, I will definitely have to post this on social media so that people are aware of the situation. Please try and assist me in repairing my DGS 130. Regards, Hendrik.
