I placed an order with highstreettv.ie on 24th June. Terms and conditions state dispatch within 24 hours of receiving an order. I have a dispatch email for 4th July but no arrival yet. The company will not provide me with confirmation of postage or even details of their company's policy in this case. They will not reply to voicemails. I received one email asking me if I had received the items just after I had phoned to say that nothing had arrived. How can I investigate this?
