Bad attitude and non transparent fees

On 06 October I received an email from Bernice Jansen Van Rensburg from aramex saying they needed documents for them to release my package at customs. I sent everything the same day and called her to find out if she received them seeing that she had not yet rep****. She confirmed that she received them and she was going to forward them to customs and she would get back to me in 4-6 days. I then sent an email on the fourth day just to make a follow up that’s when she rep**** rudely to me saying “today is only the 3rd working day” I then said I was just asking. I sent an email again on the seventh day asking why it only takes so long with aramex when other courier companies take 48hours at most. She then said “there’s a back lock at customs” this is the seventh day and she doesn’t even apologize and I’m the one following up on everything. She then sent me an email on 15 October with an amount of R500 that I was charged at customs which didn’t even have an invoice or banking details of where I have to make payment. I then had to request an invoice with banking details which was sent to me a day later...... 16 October. On the 17th October I received a call from someone saying the invoice I received was not revised and is incorrect. The same person sent an email as well saying she will forward a revised invoice. So I sent an email to Bernice complaining about the inconvenience, inconsistency and unprofessionalism. She then rep**** rudely again telling me that “it is human error and she doesn’t have a laptop she’s sharing a laptop with someone else” I don’t understand how that is my problem however I received the revised invoice towards the end of the with triple the amount that was sent. Such untransparency and bad bad service from such a big company makes me wonder if these amounts even exists or if they charge as they please because how do you make an error of a whole R1000??????
