Reported to trading standards. Zero response when I paid for an iPhone 8 stating 10 working days delivery time - which they didnt meet and didnt report. The moment I sent an email threatening going to my credit card company I get a response saying they are now forced to refund me and cancel my order - and I will get a refund in 14 working days if coronavirus doesnt delay them further! Absolute scam - clearly going under. AVOID!
