Poor Service from defy

I am really upset as my defy washing machine is still under 2 year warranty so the technician after day 1 waiting a whole day for him to pitch he comes here checks the machine and orders a part okay so 7 working days fine.... After a few days less than 7 we decided to follow up the part arrived we had to wait for the technician again... He came he replaced the part a day later the machine gave the exact same error phoned defy again booked a service again technician phoned made an appointment for 28/01 and its 15:21 with no technician we phoned to boksburg branch and a person with the name of Gugu answered the phoned my husband requested them to give us a time or the phone number of the technician as we wanted to reschedule she told my husband she cant and my husband got upset after trying to explain we cannot wait the whole day she Gugu decided to drop the phone in my husband's ear and when he phoned back she told him she dropped the phone Oh heavens I regret buying defy!!
