no delivery after 4 days

I bought a hometheatre system at russels then within 1 year the dvd broke they told me after waiting for 2 months that there is no more stock of the make I bought and that they can get a compatable but will take 3 months to get here. So I told them I'm tired of waiting and seeing that there is no manager I'm moving my account to joshua doore. The manager was very helpful when I got there but every time I come there he is either busy or there is a system problem. I decided to take a new system and told them to carry all the money that I paid on the account till now and take it as a deposit so he said its fine he must just organise with the regional manager then they can go on last week and wednesday we already sighned the necissary documents. Today on monday when you call the branch to ask when delivery will be done they just say sorry we can't do nothing now because our system is offline when system comes on delivery will be done after 48 hours if the money is paid over from russels. After I already told them that I want it delivered today. And headoffice does nothing about it.
