I ordered a boot liner for my new BMWi4 . When the package turned up it contained no instructions so I fitted it and to be fair it was a reasonable fit. However the sticky Velcro would not adhere to the boot material on the car which meant the sides flopped down. I rang the company and spoke with a rather belligerent lady who told me that there was probably some substance on the carpeting material upon which I was trying to stick the sides. I asked her if I could return everything for credit as the product was not fit for purpose. She said I could at my own expense (quite happy with that) but that Premier Products would only credit me back 75% of the £100 I spent. This is not correct and an infringement of the law. She said she would send me a liquid to put onto the fabric in the boot which would enable it to stick. Nothing turned up and I rang them again to which another lady apologised, saying that it had been forgotten, but that she would send it out. When it eventually arrived I tried out the liquid but the boot liner still did not stick to the fabric. Completely useless. I am really disappointed and would advise nobody requiring a boot liner not to deal with this company. You are wasting your money and there are better products out there. My £100 has been wasted and their attitude and trading procedures are unacceptable. Buy at your peril
