Negligence and Lack of Assistance

I'm not sure how to begin describing how bad the service I've received from Spree has been The past few orders I've made with them were all confirmed, only to receive a mail thereafter to say that x an y items cannot be received This happened yet again with their 75% off sale. I placed an order, its confirmed as being delivered and then the 'sorry' email comes. Yesterday I called to complain and one of their customer service agents helpfully advises he will order me a different item and cancel the delivery fee. Today I receive the mail to say that it cannot be fulfilled, and one minute later I receive a mail to say it will be fulfilled. So I call again, and speak to another agent who advises that I can choose a different item and she will also follow up on where a different order is......I am STILL waiting for this call hours later So I follow up again. And am placed on hold for more than 10 minutes Yesterday, I tried to follow up with a courier on where one of my parcels were and when it would be delivered. They could confirm NOTHING I am so disgusted that Spree treats its customers this way and at this rate cannot foresee that they will exist much longer into the future
