Cancellation of subscription

I have had the worst experience with this company as a bolt driver. Now I want to unsubscribe they said I need to pay R1180 cancellation fee, which I paid and sent them proof of payment. All of a sudden they are no longer responding to my emails nor are they removing me from their fleet. BOLT drivers please Stay away from this company. It has been nothing but headache working with them. A lady by the name of Tinyiko called me and sent me cancellation forms to sign and pay the amount, ever since I followed all the steps I have been ignored. And now I can't work because if I accumulate money on the Bolt app I will forfeit it to them. It seems they want to take my money *****ulently and unduly.
