i have and i think the payment terms are a joke, theytake your money but your not accredited untill you pass inspection which can take some time.
It tok 3 months first time 7 next they kept asking for more stuff, so the problem i see is that i am now due to pay for year three but only just started my accredition for year two so if it carries on i will be payig two or three times before accredited.......a joke really
