I'm complaining about a large stainless steel Travel mug, my husband brought me for Christmas, And was very happy to receive this as I have used costa coffee / hot chocolate quite a bit, the problem with the product is when you try to drink for it, it dribble out and gone over two of my White work top, So I have to use a straw to drink from this, and I think this is unacceptable. I've complained on the Costa coffee site over a week ago and haven't heard anything back, I think this is a very poorly managed site,
