I never told anyone I worked for Sigma!
I do not even want it on my CV that I worked there. HR cannot correctly identify the job role. Breach the Employment Regulations Act. Signing a contract without knowing the role was different and worded like just be additional responsibilities. People working there do not have the expectations explained from outset. I could have reeled off the customer services number of the client instead of taking lengthy complaints. I would not like to say to any customer I'll take a payment and then not deal with your complaint.
