Beware!! Faulty products and no support

Be careful of purchasing from this company. I have received a faulty product and they are refusing to help. I have spoken to the actual supplier themselves who apologised and said I should get a replacement but still this company refuses. I have been offered a refund or exchange and when I accepted that they changed their minds. I have done numerous tests and this product is incorrect. Consumers beware of this ********* way of treating customers.
