Poor service

Month end of march i was debited twice and i went to umlazi megacity store, we call the call center. I was promised that this month the will be no debit order but to my suprise the was a debit order this morning. Another problem it is extremely difficult to get hold of telkom, 10213 or 10210 u will never get through. U are told to go on whatsapp, if i do not have whatsapp how do i get them.
