Unfair Return Policy

I bought a Amacrox charger on the 4th of November 2015. I charged the laptop ok the first time. After the second charge, the charger made a noise just before completing charging and started burning up. I went to return it today, only to be told that I cannot get a refund. The only option was that I send it in for repair. <br> <br> The point is that I needed the product immediately and they did not understand and replace it with another so that I could carry on working. They said I must wait 2 weeks as they only collect for repair on Mondays. This is unacceptable customer service.
