Quality of Pringle clothes poor quality

I am 69 years of age and wear Pringle clothes since the age of 28. I noticed during the last two years that the quality of Pringle clothes is not what it was. This time I bought 3 Pringle T-shirts and was very disappointed when I noticed that two of the T-shirts had holes after the first wash. When I brought this yo the attention of the shop manager the response was that it is not a manufacturing problem so it is not their fault. Fact is a very poor quality of material was used diring the manucaturing process. After being a loyal client for many years I decided today not to put my feet into a Pringle shop again and I advise people to think twice before paying extremely high proces for a brand of which the quality very poor.
