Incredible Connection sells **** and ignore requests for refund

I've been trying to get a hold of Incredible Connection's customer care department for over a month now in regards to a faulty product that I bought online. When I failed to get a hold of them I took the product to the local Incredible at the Mall who then refused to give me a refund. On the website it is clearly stated that you can return anything bought online to any store if you had issues. which was not the case with me. Then eventually the manager decided to get back to me via email to say she will process my query to head office. Still no word from my online queries nor the store in the mall regarding my refund. This will be the last time I'll support this store and I'll make sure word of mouth will serve its purpose so that everyone I know and who ever they know will not support this store. Almost 4 out of 5 times I have issues with Incredible and unfortunately this was the last of it and made me do a bad review for them. Now I don't even have the faulty product asa the store in the mall kept it and I have no refund. And the best part is... its only R400... so what if I actually bought something really expensive. How big of an issue will it then be to get a refund.
