unfairly dissmised

Manager at Sportscene eastgate doesn't know how to treat staff, he hires and fires as he please , i never resigned , i was forced to resign , threatened by LAZI to leave my job just because he does not like me , i was even forced to draft it by hand, who writes resignation letter by hand??? when i app**** my CV was typed not written by hand by when i resign im force to type using a pen ,i was not even given a warning , at-least if can be given or go to school for managing skills as well as know how to treat people and not treat them like Dogs, i really cannot let of this matter go im taking it further than this because i never resigned willingly but forced.
