Disapointed in "Wall Paper"

In 2024 I requested quotation for wallpaper, after seeing wallpaper in the showroom. Since Four Corners Deco Emporium was cheaper than the first quote I received, I confirmed the order. I sent the wall measurement via email. Because of the renovations I requested that they keep the wallpaper and I will collect once the renovations is completed. I did a part payment last year and completed the balance of payment this year April. I collected the said "wall paper" about a month ago 18 October 2025 only to discover that it was printed on fabric. No mention was made to me that it would be printed on Fabric. I immediately contacted Gafsa who asked for pictures which I sent her. On Monday morning 20 October, i received a call from her office asking me what the problem is as Gafsa did nto fully inform the staff. I then communicated with Gafsa 22 October, explaining my dissatisfaction and requesting a refund. Gafsa advised that I cannot receive refund as i took long to collect and to complete the payment. the quote I received was for wall paper, nowhere has there been any communication that they cannot print on sticky paper. Furthermore the measurements are incorrect as it would not fit on my wall. I have stated to Gafsa my concern of applying the "fabric to the wall as it would possibly fray. I am very disappointed as I chose Four corners Emporium who was cheaper and i was impressed with the curtains i have purchased from them.
