Still no bank deduction from Telkom

I still have had no arrangements made with Telkom, why must I find my way to the bank and deposit whereas I issued my banking details.

First SMS from Telkom SA: Dear customer, Your account for customer *** has been suspended due to Collection

Why is Telkom failing to contact me for rearranging my bank details. I should I find myself in bank long queues just to fulfill and stay away from financial issues. I still regret the day I answered Telkoms phone.
