Yepme is Fraud

Yepme is fooling people. I ordered for 3 sandals and one shoe and also paid payment. But after a couple of days they sending an email stating the product is not available, They are just fooling people and wasting their time. They will show many offers and also make us order products after ordering they say product not available. If the product is not available why they are showing in display as available and they take so much time to get our money refund. We have to follow with them again and again and very bad response.
