No online delivery

I have ordered something online from Edgars on the 15th May. To date, i have not received any communication about deliver thereof and customer service is also not helping. There is no tracking online as well. When calling in today, they stated that the order is available at store however when going there, no item was available for pick up. I really do not understand how a consumer should know when her order is ready for collection but Edgars takes my money.
