NETSTAR - BEWARE OF POOR SERVICES

I have reported 2weeks ago that I had cancelled Netstar in Nov 2022 due to the car having been sold. I had contacted the call center and they asked that I send certain documents which I had. They continued to deduct but I stopped the payment with my bank. They continued to call and harass me for payment, they eventually asked that I pay R715.00 cancellation fee, which I gave them authority to deduct in Dec 2022. Jan2023, they sent message and called to say that I will be listed on ITC for nonpayment of R400+ which I did immediately. I was called last week by a consultant due to me having reported this on HP. She assured me that they will look into the amounts paid and ensure its deducted from the R715 that was required and either way the difference will be settled, or a rebate issued. Nothing happened thus far but I am being bombarded daily by Netstar from Friday last week by the accounts department to say that I owe R500+ for installments and they sent me a statement of account. to reflect such. Netstar does not have any communication policy or process within their departments, they are most annoying and even *************. My only option now is to engage my attorney and with all the evidence I should be able to charge them for harassment.
