Horrible service delivery

My issue is not with products but rather the customer service when purchasing items online, I placed an order for several items, 1 of which was a market place item and all the rest where store items which according to the website were in stock, the next day I received deliver of the market place item, all fine I expected this to come separately, on day 2 I get 1 item, I check the website to see what going on with my order and I see for reason the order has been split but the rest should arrive together the following, day 3 I receive 2 items, so I call in to find what’s going on, after repeated attempts and disconnects and explaining my self multiple times I finally get someone that says they will get hold of the store and get back me, still waiting for that call, on day 4 I call in again only to be told that the remaining items are ether out of stock or has just become available in stock and I will receive it next week some time. Don’t even get me start on the delivery guys who rock up at any time with out prior arrangement and then want through the boxed item over the gate when I tell them I’m not there, not knowing that there are electronics in the box, and had he done so I would have never have received said item because he was at the wrong address. From a service deliver stand point it would be 0 stars.
