ZERO customer service response, NOTHING. USELESS site.

After ordering a jacket online, I realised it was the wrong type so sent a mail via the site to the customer service email address to cancel order, to avoid it actually being sent. no response, sent another mail a day or 2 later, no response.Item delivered, so sent another mail with yes, you guessed - ZERO response. no online chat room, no whats app type comms platform, no number to call, NOTHING. so frustrating... Of course, i need to return the goods at my own cost and via my own methods within 10 days.... i don't know of any other online site that actually cares any less after the sale is made. i am so disappointed in this sites lack of customer service.... unless you absolutely certain you want the goods and they are correct, DONT ORDER from OneDayOnly. EVER....
