Refunds shouldn't be a pain!!

I went to @Home Centurion on Wednesday,was looking for curtains for my place,so I got them and left. I continued with my shopping in the same mall and I went Metro it's also store with home staff and I found similar curtains at half the price I paid at @Home and obviously I would go for the lesser ones. So I went back to @Home to take them back and I was asked if I have a credit card and I said no and then they said they don't have the cash to refund me with and they will take my details and let me know whenever it is that they have the money. Like I fail to understand how this should be my problem when they know very well that they sell quite pricey staff...why don't they keep enough float in the store to be able to help clients without a hassle...for crying out loud they can even keep a safe and keep the float there. Imagine the guy who was helping me even said to me "and you will have to come immediately when we call you to tell you that we have the money", and I said what happens when I am at work!?! Like I must get MY money back according to their own time. I have staff that I need to pay for and I can't cause I must wait for someone to come and buy first in order for me to get my money,don't even know when that will be,so my matters must be on hold because of @Home. I am very disappointed to say the least,I love the store and have been a loyal customer,I hardly take anything back but now they have lost me as a client that's for sure... shopping and refunds shouldn't be a pain honestly.
