Defy defective stove

On 14 Jan. 2020 I wrote a review on Hello Peter regarding the defective Defy stove that we purchased from OK Furniture, Pinetown branch. The next day a technician was sent over to assess our complaints. He confirmed that the thermostat wasn't functioning, the stove plates were not operating at full capacity and was very slow. in addition, he found a whole hosts of other faults with this brand new stove. We were asked if we would like the stove repaired or replaced. We firmly confirmed that we would like a replacement immediately. Apparently there is lots of red tape involved before a replacement can be given. In the mean time, we cannot use the oven, and we have to deal with a stove that is not working properly. And I might add that my mum who is a pensioner has to be subject to this kind of inconvenience. We have tried calling OK Furniture and Defy but we have not yet had any positive feedback. The service we have received from the date of purchase has been shocking, and that too from an established entity like Defy. Shocking to say the least and totally unprofessional!!!
