NEVER EVER EVER EVER use this company to buy anything from they are totaly useless, i spent nine weeks trying to get my money back from them for a faulty tank and have only just got my refund. I sent endless emails made countless phone calls to which you can only get hold of somebody on sales and not tech support had to eventually get hold of citizens advice plus my bank to finaly kick them up the arse and refund me.the guy on the phone just sounds like a cracked record going over the same response as if reading it from a script and will help as little as possible.as i have said NEVER EVER USE THIS COMPANY if you value your sanity and hard earened money
