not returning the item and lying

I placed an order with them and when i received it. It was a really bad quality bag i emailed them the same day that i want to return it they replied after days and said they will return it this that its been more than a months almost two months i didn’t hear from them when i emailed them they lied and said their delivery person came but i didn’t respond to them so they returned when i contacted them n told em no one approached me they were acting entitled and later a different person completely changed on his words and said we never said that we sent anybody because your area is out of our reach, basically they lied
Now they want me to send the parcel to them. I told em i paid the fee its their responsibility and issue not mine.
