Poor customer service

Their customer service is very sickening and frustrating. So every month for almost two years now I've been having problems with telkom and payments, they would not debit my account, they say I should pay manual.. I pay.. Same thing the following month, I'd pay manual until it's an every month thing. Until this 1 month they debited after I paid manual(double payment) then charge me R200 reversal fee. So now they only debit if I pay. If I wait for Debit and not pay manual, they dnt debit.. So it's jus same thing every month, I'm sick of it and cnt wait to finish my contract and cancel it.
