One of my return orders have been stuck in the UPS warehouse for 3,5 weeks now and as a result I can can get my refund back (a rather large amount!). I’ve been chasing this up constantly speaking with customer service on the phone almost daily and still nothing has been resolved. Courier serves is part of YOXX service provided to me so YOXX is responsible for any UPS delays, the communication between departments is very poor and I had to put all new orders on hold until this issue is resolved. So disappointed!!! Will not be recommending YOXX to any of my friends any more and will probably delete the app as soon as I get my money back…not worth of my time and all the aggravation
