Disappointed by Walton's Admin or Data Capture.

I am really disappointed and dissatisfied about the way Waltons back to school has inconvenienced me and handled my query. I had ordered stationery for my son who goes to Northcrest Primary, Everything was on the order page, all details and everything that was required, I then didn't receive the invoice, I had to call to check did they receive it as I saw time was passing by and the collection date was near, they then called and sent a wrong invoice with someone's details that are not mines, I called again to check what is going on ? I was then told to go to the warehouse my self and go order from there??! This is the first time I am having hassles with Waltons, the past years has been smooth, I am so disappointed as I am now going to the warehouse, so much inconvenience!.
