Very very bad customer service

i bought a bed from Coricraft Greenstone last year, a Lara king-size bed. Recently i noticed the slays are skew and the bed titled and very difficult to sleep on. I reported the situation to them on the 3rd June 2018 and they promised to get someone to check the bed. Since then, I have made several phone calls to enquire when this person will be coming to assess the bed. They eventually told me the person will come today 15 June 2018. I have made two calls to check when this person is coming and still no positive feedback. This is the worst customer service I have ever had in years. The more we sleep on the bed in the present condition, the more uncomfortable it is. Can they please send someone already? It is really appalling that two weeks after the report, they haven't done anything to remedy the situation.
