Communication barrier

I contacted them to place myself under debt review in 2017 the contract stated i can , and i was also informed i could cancel this within 5 ,working days after applying which i did 2 days after applying as i was laid of work and knew i would not be able to afford it. i was then placed under debt review on the 04/30/2019 by Abdul Carrim Khalik 0210012680. Over the years i have tried numerous times to get in touch with him to no avail i have phoned i have emailed nothing up until to date. I am now having to pay a lot of money to remove the flag from my credit report.
