Overcharge on my monthly Cheque Account Charges

Hi, I just received my electronic Cheque Account Charges Statement (No.30) for 12 June 2015-11 July 2015 which indicate charges to be deducted from my account on the 1st of August 2015. I have that my monthly charge has increased to R600 instead of R150 for my Potentiate Bundle and OD Facility Fee is R80 instead of R20. Been held for more than 10 minutes on the Call Centre phone with the accounts queries and spoken to Mbali who transferred me incorrectly without notification and then my call got cancelled. I'm currently out of town and would not have access to a nearest ABSA branch to follow-up on this query during the week. Kindly contact me on my cellphone to explain this charges in details as I do not approve of such a high surcharge (4 times my month bank charges) by ABSA.
