Poor service

I bought a washing machine last year May on July the machine stopped working I reported they sent the technician after 2days which was great service I used the machine until it stopped working this year January 18th I logged a call with builders were house they reported it to defy they promised that they will send the technician on Friday 21st and the technician didn't come I called defy call center they asked for a job number I gave them and said to me the technician will only come to me when there is onther job in my area. On Monday the 24-jan the technician came around 7pm he said the machine needs a part and he doesn't have it with him he will order it when he get to the workshop he will come back during the week and he never came on Thursday Frank called me and tell me that he's coming to collect the machine he will brought back on Friday 5th Feb I called him the whole day and he keeps on saying he will bring it since he knocked off at 20:30 until I called him around 20:00 he never answered my calls and ended up switched his phone off I couldn't get hold of him. He promised to deliver the machine 1st thing in Saturday but still now I haven't received anything he keep on saying he's in his way.
