I want my refund in full

My problem with this company hasn't been solved since they Said they will pay my money back and I know that they think they can get away with it bt they won't cos I want my money from them they may call me after they see this post bt what I don't understand as a businessman man why would you drag this and not pay ur client thier money back cos at the end of the day it's going to destroy ur business bt I guess the owner doesn't care about what happens cos he is used to doing this to his clients
