Charged twice/incorrect info from lazy call center

I paid my bill as always on 25th of month with electroniic transfer. Received sms last week to inform me they will deduct same money off debit order today, 31/8/15. Last week i phoned Telkom's lazy call center staff member who told me as the money is paid and reflects as such in my account they will not present debit order. Please note i have account for nearly 2 years and always pay manually. This morning i had to phone again and call center staff was really unhelpful and i got cut off. She did not phone back. Could not care less. I am tired of apologies from Telkom-get it right!!!!You are not sincere in apologizing.
