Most pathetic attempt to assist

I shopped from Mr Price Home Online store. We have a birthday this weekend and I really wanted to buy a specific item from the store, unfortunately it wasn't available from the local branch, they refuse to order an item for you, you have to shop from the online store and pay shipping fees, which should be a bad service complaint on its own. I ordered the item, paid extra for express shipping to ensure that it arrives before the birthday party. Today (the last day to expect the package) I was informed that the package will only arrive next week, and they cannot tell me on which day next week either. I requested to cancel the item and refund me. Next week I will have absolutely no use for the package. This was also refused. The online shop will not assist any further, as it is not their responsibility anymore. I have to wait for the package to get here, go to store to which I expressed shipped it and ask for a refund and probably lose the shipping fees. During this whole process nobody took responsibility for the problem, nor expressed any regret that they did not deliver as promised. This is disgraceful.
