Billing issues

I am very much not happy with Telkom service, each time I must call them to debit my account when there are funds in my bank account.

Last month same thing happend and I was asked to do a manual payment when I opted to be debited... Cool, I made the payment. Today is my debit date but they haven't debited as yet, next thing they will suspend my line.

This is really frustrating, just messing up my credit score.

Tried to contact the billing department but I'm unable to get through to them.

1st time having a contract with Telkom and I regret it.
