DEFY Service Centre Centurion , Cannot honor a booking request.

Centurion Service centre , I called at 8 am this morning and arranged for a technician to be here before 12. I have waited until 12h22 as no one has arrived , I called the office again the lady says she doesn't know why the technician has not come , but she will ask him to call me , I asked her what must I tell him when he calls , I cannot hold Defy staff accountable. then I said if Defy cannot assist she should have told me , then she says , she will contact him , At 14h20 I called again , I asked for a Manager, the person says you can speak to me . He says his name is Hennie , I relayed the above , he then says , we slotted you in on full diary for today , I asked him so why didn't you tell me that this morning that Defy cannot honor a booking to repair . Then he stated also you did not tell us what time you just said anytime before 12 ... unbelievable.... and now its 14h20 so what's your point . Then he states , that they are not able to contact the technician , I advised Hennie , that I will lay a complaint with Defy SA , you are indicating that if consumers buy a Defy product you have just cemented the NO AFTER SALES SERVICE ..... I mean literally no services given ... Semih Gurel your business model on after sales repairs... does not make business sense to sell a product that cannot be repaired when it breaks, due to zero interest on your BP, no follow up processes are in place to execute a professional service
