I did contact the police but they referred me back to ActionFraud. I did receive a letter from them saying that "....please be assured that activity is in progress and that no further action is required on your part...".
I have tried to contact them again but with no response to telephone or emails. And I know that several other people, including the manufacturer, had contacted them about this company so you would think that something would have happened.
I did consider taking them to the small claims court but know that they would declare they had no assets, or say they would pay £10 a month, but then fail to pay anything. I think they had done this before.
I wrote to Watchdog and the morning programme with Gloria Hunniford and Angela Rippon (can't remember the name) but didn't receive an answer from either.
I haven't contacted Trading Standards so might try them this week.
Myself and several others who were left out of pocket were rescued by the manufacturer who fitted the shutters at the original price, but people are still adding to the thread on Facebook to say they have been recent victims.
Thank you all for your comments.
