Hi I started this 'apprenticeship' at a shop 3.70 per hour found out a week later that the apprenticeship was for customer service level 2 which I already have but the boss had kept me on not on a apprenticeship but still 3.70 per hour then one lad had left and the other was about to be off for 5 weeks for a operation so it was just going to be me doing everything not learning anymore for 3.70 I wanted to leave but the boss is snide he'd tell universal credit I quit so they sanction me but couldn't carry on because of my anxiety about the whole situation now he is being funny and not paying the wages he owes me but there was no contract. Any idea how to get my owed wages?
