If you ever get a leaflet from Silkies tights saying - 'send for your free pair today' - don't do it.
I got a free pair and then three weeks later got four more pairs and a bill for 12 pounds. I didn't order them and have certainly never signed anything.
They have not provided me with their contact details or any means to return the tights.
I have told them that I am not paying the bill and if they want the tights they are free to collect them at their own expense. I feel that they are trying to intimidate me into buying them.
