evening party wears with sleeves

Good evening, I ordered two dresses from yourselves yesterday - paying next day delivery for today. These dresses haven't arrived. In the small print it stated if there is a problem with your order we will email you to let you know it won't arrive - I've had no correspondence since the email confirming my order and have no delivery either! I haven't been able to contact you on any number and the email response states it's 48 hours before you will get a response. I've waited in all day for the dresses to arrive and I do understand sometimes orders can't be for filled but to have no contact explaining this I feel is not acceptable customer service. I look forward to hearing from you evening party wears with sleeves
