Defy is horrible and no longer upholds the name they have created

I had contacted defy services after sales on the 02/12/2021 because my 4 plate glass top had cracked. The consultant gave me a reference number and said she will process my request and send a guy to get the barcode under the stove top, he had came 2 weeks later to fetch the barcode. Ever since iv been calling and getting different excuses as to why they havent replaced my stove i am so dissatisfied as i was told id have my stove before Christmas. My husband continued following up and the consultants continued making excuses, i had given up i had to make other arrangements for Christmas. I had sent emails and i have gotten no response ever since, im so frustrated , today my husband called again this time apparently there is no stock in south Africa which doesnt make any sense as the previous consultant said that they were closed and will send the stove top when they open stores. There are so many different excuses defy had given us i feel like they are trying to surpass the warrenty. Im sick of wasting my airtime and time just to be told lies continuously iv asked for the complaints department unfortunately they cut the call when finally getting through. Im so ****ed im out of options.
