Terrible service! Waiting a whole week!

Reported my washing machine on Monday. I was told Tuesday a technician can come Thursday. Wednesday my husband was told a technician was coming that day. Technician came, said he tested it 5times. I tried a load and still broken! Immediately I phoned and was told my problem was escalated. Thursday morning I phoned to make sure someone will call me. No one did! This morning, Friday I phoned 8am and was told I must wait until someone else comes at 9am because they are dealing with my problem. I asked to make sure they phoned as soon as they came in. I waited for 9:30! I phoned again to retell my problem, put on hold and put through to someone new and had to retell my problem. This lady said she would phone service centre and get back to me. I waited 90minutes. I phoned and asked to speak to her. She said she has to wait for one particular person at the service centre. I moaned at her for not phoning me to tell me that. She said she has been away from her desk! I complain about her to her supervisor. The supervisor organises a conference call with the service centre only to be told someone will phone me Monday for someone who might come! I don't know when my machine can be fixed!
