Poor quality products comes with attitude

Today we received our 3rd bed exchange since 2013. So much for quality! 1st exchange was done 2017 the 2nd 2018 and the 3rd in2019. What poor quality at a price of course and every time it comes with attitude. Today the delivery guy rudely asked “what’s wrong with the mattress”? They then brought the “ new” bed set and he said it is because the mattress bumped when they took it upstairs the 1st time that the springs got damaged! What hog wash?? Or is that the poor quality customers need to deal with??? This is an inconvenience for us as we need to make all the phone calls etc because of poor quality and then you get treated like this??
