I had the same problem with them, they kept sending me letters every so often saying I owed thousands of pounds in fines etc, eventually after speaking to them about 5 times they cancelled all the fines. They are hard work to deal with but you just need to keep being persistent. The fella i spoke to eventually was great and cancelled the fines on his computer there and then. Might be worth to keep ringing up until you speak to someone who will get it sorted there and then
