Poor Sevice

Good day,

I purchase on Mr price online all the time. this has happened to me several times and now I am highly frustrated. You add items to your cart , money is taken from your account, a day later or so they send you an email of no stock items..... Why does the website not advise you of no stock items before you pay or checkout!!! there no no customer satisfaction and further to that take sooooo long to process the refund... Im tired of bad service!!!
