Shocking

I bought a new washing machine at House And Home. The washing machine was making a very loud terrible noise when spinning and its shakes like crazy. All of a sudden it started leaking and shaking more than before. The noise become so loud that you cant even hear yourself thinking. We logged the complaint and received a SMS from DEFY on the 27th of July. After that 1 technician made contact and an appointment was set up, funny enough nobody pitched. Then after that again I had to phone them to make an appointment and I told them that someone will be home Wednesday (yesterday) and Thursday (today). When I phoned them today they promised me that a technician will be attendig to the issue today and again nobody pitched or even phoned to reschedule. This is terrible service and shocking to know that customers are treated like this. When will this be sorted out?! Im sitting with a brand new washing machine that I need to pay every month that I cant use
