think people can stay out of work to please them

I logged a call 04/04/2016 for my under counter oven that is not working with ref no Customer Resolution Centre #207779..(RU-DE-***) i got a call ***)from several people claiming they are from master care. they advised they will be at my place 08/04/2016. I then stayed out of work waiting for them. I called at 12:06 on the 08/04/2016 and the rude woman Dianne told me i must just wait they will come. nothing. On Tuesday 12/04/2016 I logged a complaint again with JD and got a response from Nathan Cloete, all of a sudden the Wednesday Doreen from master care calls me all ubrubt for someone to be at home the thursday cause they dont work weekends. I then arranged for someone to be at the house both thursday and friday after calling and leaving Doreen several messages that the person is waiting for them to no avail. Today i get a call from Moses advising i must be at home monday? Am i an idiot to stay out of work or pay people to watch and wait for people that dont come. I gave my cousin R200.00 just to wait for them and to this hour no1 has come. Now what makes me mad is the same thing happened with my machine and we know how that went down! must i stop payment again!
