Query: Shampoo

I have used this shampoo for 5 years . This is the first time I have ordered this thru Amazon, and am very dissatisfied. The shampoo and the conditioner I purchased are very old , which gives this product a very stale smell. The shampoo has also been diluted to half it's strength by whoever distributed this for Amazon. Your help in this matter would be appreciated. Thank You
