Bad attitude after they made a mistake

I upgraded my contract on 1 March and received excellent service from Vodacom Fountains mall.I was contacted today to tell me my phone had arrived. A few minutes later they phoned back to say they had ordered the wrong phone and would phone me back in a few minutes to see what we could do to sort out the situation.hey never got back to me and when I went into the store was met with a horrible attitude and told that I would just have to wait another week for the correct phone.The young man who had helped me previously ignored me and would not see me. A better attitude would have gone a long way. I know that everyone makes mistakes but owning up to a mistake and trying to assist in fixing the problem asap does not cost anything.
