Client Service says I cannot buy online

Last night I wanted to buy an item, which is not available in my local store, although it says that it is available in the stores on the website. I added the item in my Cart. I was just ready to make the payment, the website said something about maintenance on the website. I tried a hour or so after that and it still said maintenance.

This morning when I tried the whole website was looking different. I didn't get any notification on the website that they will be upgrading the website, which is the logical thing to do.

The item was listed as in-stock in Cape Gate Store, but when I went into the store they told me they don't have it. Days after that it kept on saying In-stock. So I phoned the Client service, they told me there is nothing they can do, I must order it online. So that is what I tried.

I've phoned the call centre again (spoke to Lisa) and they told me the system is still busy updating and I cannot buy it. I cannot recall any apology for the inconvenience or anything and this is a call centre. This is now about 14:00. I tried to buy the item at 10pm last night and was kicked out.

The password recovery function also does not work.

As far as I know there is limited stock, so now the system stops me from buying the item. I need the item.

What must I do now?..and what if the item run out of stock. I've tried for a while to get this item now?
