No feed back on warranty product and have to pay currier fee for to send away away warranty products.

What poor service, I bought a PlayStation4 for toys r us Kimberley about 2 months back and the remote was giving me problems with buttons not working. I took the remote back in order for it to get fixed under warranty, after 2 weeks of returning the remote I haven't heard anything back from them. I phoned to check the progress, they said they are glad I phone because they lost my number and they ask me to pay the currier to send away the remote. They try to help and said that they feel it's not fair for me to pay any fees because the remote is under warranty. So I let them go their way, after a week i went back to the store where I met the assistant manager, she said that head office confirm'd to come pick up the remote. Three weeks later and still no response what so ever, I phoned again and then they came up with the same old story. It's seems like they are dragging time for my warranty to expire. I am very unsatisfied with Toys r us. This is how they loose business.
