Account Paid in Full and charged for bounced debit order

Please can you assist me with the below.

i have a big problem at the moment with vodacom, i paid my my vodacom account earlier on the 24th Decemeber, as agreed with vodacom the debit order is to go off the 25th December vodacom debited my account on the 27th December which is late and not the agreed upon time.

we have phoned so many time and no one is willing to assist us, the collections department is being full of **** and is giving us a lot of attitude, Pheliswa was rude and says that she is reading the terms of conditions when we ask her to read the t&cs and to send it to us she avoids the topic,

when we were still busy have a heated conversation with her she was saying thank you for calling vodacom we haven't even finished our conversation, but she wants to end the call.

Why is it that if we paid the account earlier then the date that the debit order went off it is a problem and i am being charged the R100.88 fee for a returned debit order, we are getting no where with vodacom and this is starting to get my blood boiling!

if i didn't pay the full amount i would understand or i didn't pay, but i paid and i feel that this is not the way a business should be run.

we have asked the collections department in the t&c's where does it say if you have paid you will still be liable for the fee, only if it has bounced, the first lady Pheliswa said it says that in the T&C's we requested that she shows us, the supervisor said there is not T&C's like that, so what is the truth???

if you go on my account you will see that this was escalated on monday or tuesday and i still have not received the feedback i have asked for. it has taken me numerous phone calls to sort out this with only getting rude and unhelpful consultants. i am sure this is not the service vodacom would want to give their clients.

i as a paying client has my account up to date and now you want to charge me, sorry for you not going to happen.

Please can you resolve this issue immediately or i will be taking this matter further then Hello Peter.
