I have been waiting for my refund for almost 3 weeks now,

I bought the couches cash from Rochester Centurion Mall, but upon delivery only to find that they are too big for my room. I asked the delivery guy to take them back but they refused and told me to go back to the branch I bought from and let them know that they don't fit my room. the next day I went back to the branch and explained my problem to the sales lady. she then informed me that she will arrange for the refund and the delivery guys to come back to my house to collect the couches. I sent them all the requested documents for cancellation the next day and I was promised that the couches will be collected. it has been 3 weeks now and every time I call them they give me excuses for not collecting the couches and when I ask for my refund I was told that they are unable to refund me before they can collect the couches. the branch don't want to give me the exact date they will collect the couches in order for me to get my money back. it has been 3 weeks now and when I offered to bring the couches back myself since they are unable to collect them but they refused and told me that they will not accept them. the staff members are now getting rude towards me, one of them even asked me what must he do with the couches whether must he take them to his house. I tried to explain that the reason i cancelled the transaction is because the couches are too big for my house and I dont have space for them but Rochester they just dont care.
