N11 Sent Me Low Quality Towels - Rejected My Return Request From Doorstep

I ordered towels that were on sale instantly from the N11 website. I was shocked when the product arrived. They sent me a very low quality product that was different from the picture in the ad. I created a return request to be picked up from my door, they did not pick it up on the date they stated. They sent me a notification saying you did not deliver your cargo, cancel the return and create a notification to be picked up from your door again, they still did not pick it up. They deceived me again by saying that the return from the door can be received at most twice and usurped my rights. You failed at least 11th grade and it is a cheap and simple course, but there is something I forgot, this course was compulsory, customer satisfaction. The term will need to be repeated
