Bad customer care

I had bought a hydro vac compact from verimark. When I used it at home with all the accessories it didn't want to pick up the dirt so I took it into verimark they said it takes 16 working days but took like over 30 working days to come back the Chatsworth centre store refused to test the product out. I brought it back home and used it and still the same. I took it back and asked the store to see what I'm experiencing at home they said no. They took it in again I sent the vacuum in on the 4th November and only when I called on the 7th the manager was on lunch Christine Moodley and the guy that worked there said he's new and has to consult her and get her to call me I waited no one called I then went into the store on the Saturday to see the manager Christine Moodley and she was on lunch and I was told 15 mins she would be back she was back 2 hours later from her lunch break. She also then told me that my vacuum was in but I got no call her response for not calling was she was busy. I asked her to please check the vacuum before I leave and she brought the accessories of a different vacuum cleaner when I asked her to use the accessories of the display her response was it's in the back and is too much effort to take it out but she will call the repair place and ask them what was wrong and call me. Yet again no call I called on Thursday the 14th Dec she was off I asked to get her to call me she didn't I called the Friday the 15th at 12:20 she was on lunch I called again at 13:20 she was still on lunch I went in at 14:20 she was still on lunch she only came to the store at 15:45 I waited in the store for her to get hold of the area manager at 16:15 till 16:45 she said she's going on lunch yet again. She's so busy taking lunches that she can't call customers to collect their items.
