I spent over £500 worth of products in April 25 and they have not sent it out. I contacted my bank after reading all these recent reviews as I think I have been scammed. The banks now says I have to contact citizens advice because the can't refund me because i bought from them before and the received products. The emails I am sending are bouncing, the contact number does not work and the tracking number for one order is still the royal mail is waiting on receiving it. Yet they sent me an email asking for a review on what I've bought. Also the site is now saying it's temporary closed. Can anyone help with this please?
