I have been teaching a student through an agency since last October. We have not done many lessons as she often cancels at the last minute, but according to the agency owner I am entitled to be paid if cancellation is less than 24 hours prior. I am supposed to be paid through the agency, but have not received a penny so far;they now owe me over £200 pounds. The owner said he was processing my payment a month ago. I received nothing. Then he said he had not got my bank details. I re-sent them. Then he said he was speaking to the accountant to get an immediate payment. Two days ago he said the payment had been processed. Still nothing in my account. I have told him I cannot teach the student again until I am paid. He then sent me an e-mail saying the student really likes me as a teacher and has paid him for another course of lessons. I really like teaching this student and feel awful as obviously none of this is her fault. I have had to make excuses when she wants to book another lesson as I am adamant about not doing any more lessons until I get paid to date. I'm upset that this reflects badly on me. Should I explain the real reason that I am not continuing with the lessons and is there any legal action I can take to get the money I am owed?
