unemployed because of gym company blacklisted me

<p>It was sad to find out I can't be employed, I was informed be a job agency at the interview that I was blacklisted by a gym campany from which I didn't know about because I never registered with them or received a letter of warning or sms from them saying I owe them R 8200 ,after the interview rushed to them when I got there my signature was ****d even the hand writing was not mine ,they also said I'm working at the fnb which is not true because I'm not working ,I was asked them to check whether the system shows if I attended the gym or not because I don't have the excess card ,they checked and they said they had the excess card with them, so I don't what do because I'm unemployed now because of them</p>
