Over a month waiting for a repair

I logged a complaint about my refrigerator over a month ago and till today my fridge is not repaired. I called the jhb offices and spoke to a lady named Lesego and she told me a technician will be coming over. It took a week for a technician to be sent. My complaint was about a bulb but I was not sure what. The technician checked the bulb, then the holder then told me the fault was the bulb holder and said he had to report it to the office, they will then give him the replacement or they might have to order it. It took another two weeks which I then called to ask what was happening and the lady told me the technician will be coming on Wednesday that week. He then came but to my surprise he told me his car was broken into and he can't find some of the staff that was in there including the replacement. So he had to report this to the office. Another strange this was him turning up at my house two days later unannounced and told me he was there to replace the holder. He then discovered the fault was not on the holder. He told me he needs a second opinion. He left some part out without putting it back. I then got a call from Defy telling me they gonna send an inspector on Friday.
