Homechoice becoming Horrible Choice

Ordered a laptop on the 20th of last month, 1 week later when I called to track my order. I was informed my order is being sent back to the warehouse and will take 2 weeks to get back there. This is because the delivery driver couldn't get hold of me. How? I received no phone-call from the driver, don't they use WhatsApp if they can't get hold of a recipient? I stay in an Estate, why was I not dialed from the gate? Now its been 3 weeks, can't order another laptop because I have to wait for the initial order to be sent back to them. Now am being held hostage here, can't do nothing and must wait for them to update their details 1st. When I phoned, I asked them to send the laptop back to me and offered alternative numbers I can be contacted on. I was told to go to the police station to certify my ID if I wanted to update my details. I did and send everything to them, to this day I am told they still waiting for the laptop in their warehouse and therefore I cannot get another one. I missed my assignments because my usual laptop crashed, now its taking more than a month to utilise the credit they granted me. they are very expensive to start with, you pay 3 times the normal price with these guys yet they provide such horrible service. I think I should just walk away here
