I received one today 13th July which was dated 9th July. They state that they have already tried to contact me with regard the alleged infringement. The are accusing me of downloading a track called "Infinity by Guru Josh". I had to Google this to figure out that it was an acid hose track from the 90's?! Why the hell would I want to listen to that let alone download it? I have forwarded a copy of the letter to my MP Norman Baker and also have made a complaint to the SRA. I will be sending a letter back to ACS:Law categorically denying the infringement as advised by BeingThreatened I would advise that anyone else that receives a letter from these people also contacts their MP and also makes sure that they respond to the letter politely and calmly. This company is a disgrace to UK Law and will eventually be put out of business, but in order for your voice to be heard, you first need to shout. You can do this by emailing your local MP. To find out whom your MP is you can simply go to this website and just enter your postcode. Remember. Don't panic. This is a [problem] plain and simple. Treat it as you would a spam email except contact your MP and more importantly reply to the letter from ACS:Law politely denying it.
