Delayed service

I ordered boots at the beginning of August, and I haven't received my boots yet, I asked them about it, and then they gave me a excuse in saying they had trouble with the courier service, in a delaid email. So I replied in saying I would like my money back, they said they can't do that as they will be losing money, but the fact is I'm the one losing money. They didn't even apologize and say that they will make a plan to get the boots to me as soon as possible. They also said if I want my money back, I could return them, now would I have to wait two months for my money back or how ever long it takes as I'm still waiting on my boots. And would I have to pay to send them back? I will definitely not be purchasing from them again.
