terrible billing practice - double billing

I find it highly irregular that deductions are made before a due date. When opening my account with Telkom i clearly stated that my debt dates are to be on the 25th or after, not before as my pay date is the 25th. and not ever before that. now the 24/4/2015 Telkom attempts to debt my account and unfortunately thee is not enough funds in my account because I have yet to be paid. so firstly it bounces, causing charges on my account which now become my cost.<br> Then I get an sms stating my account is not paid and it needs to be paid into a Telkom account within 48 hours otherwise my account gets suspended. Contacting Telkom they give me account details and I make full payment. Now come this morning, 30/04/2015, I find that Telkom has debited my account with the full value of which I have already paid.<br> I contact Telkom this morning to find out the situation, to find out that Telkom had handed my account over to their debt recovery division.<br> Now.. I have to be contacting Telkom for all this nonsense, spending my time and effort tracking down my own money, my bank account now has charges it should never have had, and my account was handed over for lack of payment with no due cause!<br> TERRIBLE
