Telkom's Incompetence and Disinterest

I took out a 24-month contract for R139 per month to be paid via debit order. When I lost my part-time job (my first in a very long time), I had to cancel all of them. However, the cancellation requests were ignored by my creditors or I was charged anyway. My bank account became very overdrawn so Standard made the decision to close it and write off the charges. I notified Telkom, continuously following up with them in every way and on every platform possible for months and also their debt collectors. All I ever got was more invoices with more interest and a query number. Now I have a final cutoff notice. I am up to date with payment.
