Inefficiency and lack of communication

I made an order for items online (Boardmans store). the order was confirmed to have been dispatched. after days, I called the online team to find out about the package. they promised to get back to me but never did. I then called the store directly who informed me that the packed was returned by the courier and promised it will be delivered the next. I have still not received the package and I have been contacting them constantly and they keep making promises which are not being fulfilled. I am extremely disappointed with the inefficiency of customer service. I will never use the online store shopping anymore.
