Colis non distribué alors que le système de suivi indique qu'il a été livré

Good morning,Over the last few days I have been doing my best to try to solve the problem of my parcel not being delivered directly with GLS (Parcel number 92568398718).I wrote to the customer service and, with the support of the consumer association (TestAchats), opened a direct forum with GLS.The problem has still not been resolved and I am really fed up.That is why I am sending this e-mail to request a refund for the products that were never delivered.I am also finding that your customer service is very bad.I find regrettable that, since I informed you of the problem on 01.09, you have not dealt with the situation in a serious and responsible manner.I look forward to hearing from you.
