Poor customer service with no support at all

Do not ever make an online purchase with these people. Once you have paid you get no communication on the status of your order. On 6 April I ordered 3 (sonoff) items to the value of R737 which included R80 delivery. On 11 February I made an enquiry on their website as I had received no response after payment. On 13 February I received notification that the parcel is being packed and was going out for delivery. Once received several days later I installed these and one of the basic switches were faulty. I sent an email to them on 29 April advising them of this. I have yet to have a response to my email. They deserve no stars
