EXTREMELY BAD SERVICE. DO NOT USE

I placed an order online for a laptop on the 27th November. Delivery is supposed to be 3 to 5 business days. I received an sms that the order is on the way to me. Then a few hours later another sms to say that they cannot deliver. I have called customer care everyday from the 1st December. All they tell me is that they will escalate. I have requested numerous times to speak to a senior person to find out what is happening with my delivery. I have been given **** email addresses and phone numbers that no one answers. No one can tell me where the order is. Custoner care says that on the system it shows that they tried on 2 occasions to deliver but no one was home. This not the truth as they need to call me for an access code for the complex in order to deliver. And if by any chance they do come in, my front door bell is linked to a camera and to my phone. No one has tried to deliver. I am frustrated and angry.
