Lies, lies and more lies

Today i received and email to say. ORDER ready for collection. Yay what a great way to start the morning. Upon arriving at the warehouse to collect my gift, i was told. OH no we sorry. Its actually not ready for collection. This is now the third time this has happened to me. I then requested that the tiems be delivered to me free of charge to be told. "Hi Adam, kindly note that due to the items already being allocated to the collection, we, unfortunately, cannot change this to delivery. We are terribly sorry for this inconvenience but will take this up with our warehouse team." This is absolute *******, you stuffed up and i must suffer the consequences. Either deliver the items to me or refund me in full for the items and i will happily support a retailer who cares about their customer base
