Poor customer service

I’ve been having a problem with my washing machine it was not completing the cycles since August 2025,went to makro meadow dale where I had purchased it and they logged a call for me at defy,the first technician that came said it was water pressure in the complex which didn’t make sense as to why would I be the only one having that problem so he didn’t resolve my issue,Had to log another call at the makro branch again they sent out a technician problem was still not resolved,I than called and another technician came amd said it was the valve and said he will inform them at the head office to order the part so it could be replaced.He than came to replace the valve,the machine worked for about 3 weeks and it was back to square one.On the 4th of November I called the defy offices spoke to the receptionist by the name Thando and related my concern to her and she logged another call for me I than told her that we have been back and forth and the technicians are failing to fix the machine therefore I would like for it to be changed and she said a senior technician would be sent.The technician came on the 5th November 2025 and he checked the machine tested it and saw that indeed the cycles were not being completed he took videos and pictures and said he would report back to his manager that I’m requesting for the machine to be changed.Yesterday 12/11/2025 a machine which was supposedly new came to be delivered and they took my faulty one,to my surprise when we opened the machine it was a second hand machine with dents and scratches and the pug was incomplete.I than phoned defy and spoke to Tshegofatso Kgoloko and he gave me his email address to send pictures and said he would call me back shortly.3 hours later he still hasn’t returned to me I than called with no answer and called their reception and Thando put me through to Tshegofatso and he said they will bring back my faulty machine and take their one and next week bring another machine again,what an inconvenience and how do I know they will bring a new machine or another second hand machine again.Im very frustrated about this.
