Broken cell phone

Bought a cell phone at Mr Price cash in on the 21st December, within 2 weeks it broke down and have since returned it to the store its been 5 months and they cant fix or give me another phone. I have been to the store with no help also send email to customer care department only to be told to go back to the very same store where I am not assisted. talk about rubish service on the next level.

Mr price please refund me my money seeing that you cant fix the phone or replace it.
