terrible customer service by a staff member

<p>I called the branch to ask them about a taķkie that I bought the day before but had to change the size.was told by the assist that there was a size available.So I went to the store first thing next morning, just to be told he made a mistake. I was so angry and he promised me there would be one later that afternoon and he would contact me.then I asked for another pair of a different brand, once again he made me come in and there was nothing..so I spend my time and money driving up and down to a store who says they have stock but in the meantime there is nothing.what type of service is this and why do they even ha en people working for them that's so unreliable and don't know what's happening in their stock rooms.if you need training please speak to your manager.you cannot let a client come in every time and then be told you made a mistake.im so unhappy with this persons service I've been getting brilliant service all the time but when his In the store you know something will go wrong. Unhappy I have to come to n1 all the time for nothing.please sort this out ASAP</p>
