Thank you for the reply.
The problem is, I was the technician who developed all of the software up to the point I left. They have replaced me with a college leaver who has no experience and they are still using my name. this is sullying my reputation within the industry and will almost certainly cause me issues in the future. They are also lying as to the qualifications of their staff as well as those of the directorship. They claim ISO status for staff and software yet this is a blatant lie and when associated with my name will bring me into these lies. I am just an honest guy who works hard and want to continue but these are salesman who are just after the quick return and then to move onto the next thing leaving destruction in their path.
