The customer service provided by Glaxosmithkline Holdings is excellent. I recently contacted them with a question about one of their products and they were very prompt in their response and provided me with all the information I needed. I was impressed with how knowledgeable and friendly their customer service representative was. Overall, I had a great experience and would highly recommend Glaxosmithkline Holdings to others.
