Un-authorized additional cover

I am very disappointed with cartrack, I subscribed in May 2023, with the premium of R169.00. then on the 25th July 2023 , cartrack debited R224 and he following months, I sent them emails of clarity as to why the premium went up, they didn't respond. I then called on the 18th January 2024, my call was answered by Bongiwe , she said I took an road assistance with Asiphe on the 5th July 2023, I told her I donot remember that, can she please send me the recording of that call, up to today, she didn't send the recording. Then on the 03 April, I called them again, my call was answered by Sheila Alexandra, I explained the same thing, she said she will request the recording for me and I should expect it in 72 hours, until today I didn't get that recording. I cancelled cartrack debit order in my account now Iam being called by lawyers left and right demanding that I should pay cartrack company Iam in arrears, to avoid my name being sent to administration. I have been continuously responding to emails I've been getting from their lawyers, and also continuously sending emails of enquiry to cartrack with no success. I feel very much abused by cartrack, when I try to cancel the contract, theres this huge amount that appear on the forms they sent me that I must pay, should I wish to cancel.

can you please assist me regards
