The Source Metropolis at Metrotown

I bought a Nextech memory card 4 in 1 adapter from them, and it stopped working when I was transferring data to it. I had the reciept and went to return it (I read the return policy on the back which stated they accept it back within 30 days) I bought it on July 20th, and took it back on August 9th) I only used it once before the 9th. The employee informed me I was wrong about the return policy even though it said everything in fine print. I didnt want a refund. He said he wouldnt back up what
