PATHETIC SERVICE!!!

Since August I have been trying to cancel one of my contracts with telkom. A week after submitting a cancellation online I received a mail saying they received my request. Nothing further ever happened. I tried calling them every day but I am on hold for 15min then they drop the call, I call again, on hold for 15min then they drop the call. I was lucky enough to get through to them two weeks ago upon which the lady that assisted me said she is doing an immediate cancellation and they will be in contact with me. I was billed again for this contract. I will be goin to the bank to reverse the debit order, and I will keep doing this until my contract is cancelled. I do not care that telkom will deactivate my services if I do not pay but at least they will call me for payment - if that is my only resolution to get hold of these people because they only call me to ask me to upgrade and apparently the upgrade department has no idea how I can get hold of the cancellation department.
