Online order Hifi Corp

Cant even rate it 1 star . I bought a toaster on 25 Feb online. I changed my delivery address on 8 March. On 14 March it was delivered to the wrong address. I have sent numerous emails, i have chatted more than 10 times online with a wonan called Chelsea, they eventually changed my address and this morning 3 June it was returned to sender. There is no answer on their phone no, i dont get any joy out of emails, complaints on Facebook of the online chat. Al i want is my order. Please DONT EVER ORDER FROM HIFI CORP ONLINE
