Beware of Hifi corp online. failure to deliver

Shocking poor service. I ordered a lap top online from Hifi Corporation. They said it would be delivered within 2 days or so. Next thing I knew I received an email from Hifi Corporation informing me that the lap top had been delivered. That was a lie because I had been home all day and no such delivery took place. I immediately responded to their email and informed them that the lap top was never delivered. No response. I then called them and they said they would lodge a complaint with the warehouse. They said I should expect a response within 48 hours. 48 hours came and passed and still nothing. I called them and the agent said he will escalate but he has no other answers for me (imagine that). Still waiting to be contacted about my own lap top that I paid my own money for. I sorely regret not buying it through Takealot because they deliver fast, their customer support service is reliable and responsive and there are no stories about "warehouse this and that". They understand that a customer does not care about warehouse and other business arrangements within the organisation, the customer only wants their complaint resolved promptly by the shop they bought from. But Hifi Corporation does not understand that. Why would I care about warehouse not responding etc? As far as I am concerned a lodged a complaint with hifi corp and they have not made any effort to resolve it. If you are going to offer goods and services online, you must also build appropriate customer support structures to encourage more people to use the online shop. This is the worst online shopping experience I've ever had and I'll never again buy from Hifi Corp online. I'll stick to tried and tested merchants going forward.
