Telkom is disappointing!!!!

Good day I would've never ever resorted to writing a Hello Peter complaint however you guys leave me no choice. I've had a contract with telkom for the last 8 years.. And my debit order isn't taken outvcorrectly.. Telkom decides to take money off my account whenever they feel!!! I have opted for the 20th of every month and to date I've been having endless problems with Telkom taking money as if and whenever they feel they want to. Its now the 29th and no money has been debited. I even tried to do manual payments with you guys and that didn't work. Not sure what else to do. I've called the call center last month only to confirm that on the 20th of July you guys would debit my account. This is one of SA's most reputational cellphone and landline company however you fail to fulfill on one simple instruction!!! No one really calls you guys out to debit their account yet I'm here begging for you guys to take the money from my account.I've got Fibre and a 36 month contract with you guys im afraid i would need to cancel if this complaint is blindsighted! This is ridiculous and frustrating!!!!
