Conradie appliances for worst service experience

JP responded to a call for our Siemens dishwasher E19 repair in November. He fitted a valve and informed us the motherboard had to be replaced as well. He subsequently ordered the board, which we paid for. R3260. Then he disappeared into thin air. He said he was ill at one point Thereafter both numbers 0845116770 and 0842086696 went straight to voicemail. We even went to the address in Strand( a block of flats) 18 Haylett Street. Tried to contact him on Facebook and email. Zero response. Zero communication
