they supply me with two damaged wifi routers

I bought a wifi router since 02/02/2015 till today the 13/04/2015 I have never had the joy of using, it was faulty when I bought it they send it to the repairers 3 good times it still came back faulty.The worst part now is that they are refusing to give me my money back.They insist I should keep on waiting for this product to return.They have have been so inconsiderate of the fact that when I bought a wifi I wanted to use it from the 02 of February .I was not buying it so that I CAN USE IT SOMETIME IN JUNE OR MAY WHEN IT RETURNS FROM THEIR REPAIRERS. I'm disappointed,frustrated because I'm unable to work from home and getting broke because I've been going up and down to four ways mall complaining about this issue.Matrix Four ways doesn't care about what the consumer protection act says about a customer returning a product for the 3rd time.They think their above the law thats why they refused to give me my money back.
