Debit other mismanagement

During December they debit your account early and costing you money for unpaid debit others of R100 and also charge you an extra R50. 00 for late payment because they don't on your payment date. I had two contracts with Cellc one was debited after the my pay day and it was paid correctly I got paid and the other one not. As a results I am canceling all my contract with them. They delay the process of canceling and claim to request details again and I already gave them the information and the notice because they wanted to continue to debit my account. I am so fed up with this kind of service especially during this period where everybody is struggling financially with the pandemic and cannot afford to waste money because of unprofessional companies. Till todate Cell c never responded to my emails letters of concerns and cancelation. Such horrible service
