Seasonal worker but was not paid up until today

I was employed by sportscene during the seasonal period. I was only issued one contract for a previous week of which i was paid for. Because they had no staff at that time i was asked to work for another week i did ask about another contract to be issued out but i was told(Chantelle) i shouldn't worry it gonna be sorted but up to this date i was still waiting and begging for them to pay me. Ive been liasing with chantelle n she has been promising to pay me of which she had failed dismally. This upsets me a lot because i was dedicated to my work as i was on a 9hr shift. This makes me feel like i was a volunteer. I lost my phone i would have shown u the messages n replies that i received from her. I even told her i was gonna call head office to report this matter and again she said she will sort it out it has always been i will try by next week and that turned into months. Before i could even write on this site i told her to not bother herself about me since she has failed to pay me my money. And i didnt get any response from her and im not surprised. Sportscene is a well known store and for them to treat me like this i dont think it fair. 9months is a very long time
