Lewis Pretoria North is borderline ********!

So this store took my money for a couch. I come back and they refuse to give me my couch without a further payment of R2000. Because I feel so grossly mistreated, I refused to give them anymore of my money so they tell me to take my money back. I agreed and they tell me that they do not have cash in the store. So I'm back a week later and they are telling me the same story. They say they've tried calling and emailing me but there is no email or missed calls. I am truly heart and disgusted by the way this store does business.
