HI Iris,
I'm in a similar situation to you. I bought a dashcam off living social/ef mail on the 2nd december to post off to poland to my friend in time for xmas and it has not shown up to my home in london and ef are not replying to emails asking for information.If the truth be told i think it is not uk held stock and is poss being sent from china as all directors are chinese. Last time i bought some razor cartridges they took a month and came from china but was not ef selling them. I think a lot of chinese list on living social knowing they have no chance of matching the 7 working days delivery promise as it is not UK stock and needs to be and from abroad.If you were lucky and paid through paypal open a dispute with them and get a refund or if you used a debit/credit card ask the issuer to help you get your money back. I paid through paypal and have told living social if no camera delivered by mid day tomorrow I'm opening a dispute through paypal and asking for a full refund as i do not want the dashcam if it is not here for posting off to poland and will buy one for cash from maplins and post that off intead. Good Luck with your dashcam Iris. By the way ef's email address that you are using is correct customerservice@efmall.co.uk and mine were going through without bouncing back to me so perhaps you should check the email address again
Michael.
