Staff do not inform clients properly - Consumer Complaint for PEP STORES

I bought a paxi bag from pep and did not use this as I had to send via postnet and could not use this bag any more.I did not open this at all. When I wanted to return this they refused to take this back. Saying they dont refund this bags but they also did not inform me about this when i bought it. I dont understand why they can not take this back and re enter thus into stock????? Or is this just easy way out?
