VERY BAD SERVICE FROM AEG

I bought a AEG Gas Stove from Makro in February 2017. 6 Months in using my stove my rubber broke. I immediately reported the fault with AEG as my stove has a 1 year guarantee. This is in the beginning of August 2017. They immediately came back and said a technician will come out in 24 hours. We waited a week. Phoned them again and they said no another technical will come out in 24 hours, we waited again. We then phoned the technician directly and he came out to look at my machine. Never giving us any feedback, we waited about 3 weeks for him. We then phoned AEG again, and they said they do not have the part in stock, and I must wait for them to get a part. I kept on phoning them on a weekly basis to ask when they will receive the part, and they always say sorry the don't know, we must just wait. It has now been 3 months going on, with no replacement. Seems like AEG cant repair their own machines, and rather must leave SA again. My new stove does not look new any more as when I am closing my stove it scratches. I spoke to so many people at AEG but they just keep on telling me sorry there is nothing they can do , the need to wait for parts, and they will phone me back. 3 months now and I am still waiting for the parts and the phone calls. Please people do not buy a AEG Machine, as when the machine brakes you are on your own. Your guarantee means nothing. Rather by a Defy machine. Even the supervisors never phone me back from AEG. I am hopeless and do not know what to do, so mad at myself for buying a AEG product, will net buy one or recommend one again.
