multiple loan debits on irregular dates

To whom it may concern, I have a loan with the credit customer assist department and I have been trying to contact/complain/resolve several issues for some time now. I have as of today spent in excess of 300 rand on airtime simply trying to contact you guys. I appreciate that there is a pandemic at hand and I appreciate staff are spread thin but to sit on hold for 20 minutes every time I call (not to mention the dropped calls that no one even bothers to call back on bar the select few) is simply unacceptable. SO, to address the situation at hand for the umpteenth time...Firstly, this loan repayment is scheduled to go off on the 28th of each month and for the last year i do not recall it ever being debited on the same date which makes it very difficult to budget for. in the past i have been negligent with this payment but for the last 6 months i have been more than diligent with this repayment ESPECIALLY CONSIDERING the these have been the debit dates for the last 6 months: 6 February11 March24 April25 May4 June30 June I cannot fathom how an established global financial institution can take free reign over my finances to chop, change and ultimately decide when they feel free to take whatever funds out of my current account. To say i'm lividly frustrated is an understatement. Furthermore this has left me financially crippled at this date in the month. I have logged multiple calls and STILL NO ONE GETS BACK TO ME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! AT THIS POINT I HAVE NOW SPENT ALL OF MY AVAILABLE AIRTIME ON TRYING TO RESOLVE THIS. Today, after holding for in excess of 35 minutes i was rerouted through 3 departments to ultimately have my call cut and with 2 rand remaining airtime it is pointless for me to try and reconnect. I need the debit for the 30th of June reversed immediately and for someone to contact me telephonically to explain to me why this loan is debited so irregularly and why after asking for 3 years no one is able to provide me with a statement or any information pertaining to this loan account. this should be linked to my online profile. to add insult to injury, my mother was employed by Standard bank for the last 3 years, at a very senior level and she was unable to source any additional information for me and my family has a collective investment worth within your bank of close to 100 million rand and i am appalled that my high wealth family members receive considerably greater customer service than myself... does this mean your interest only lies with your high wealth customers and the rest of us paupers must just deal with the bottom of the barrel in terms of customer service??? The only constructive feedback that I received from all of my attempted communication was that I was debited twice as an outstanding amount is due for january. THIS BEING SAID... I would like to understand firstly, why no notification was issued to me regarding these supposed arrears and secondly, how a financial institution can justify debiting a customer for an arrears amount 5-6 months after this 'non-payment' occured. LASTLY, if you take a minute or two to review my statements you will note that i am in the process of settling a large amount of debt and for the first time in 10 years feel as though i have a grip on my finances UNTIL standard bank decides to take what they want when they want. this 1441 rand is my disposable income for the month and to be frank should the account actually be in arrears (from god knows when) is it so unreasonable to expect some sort of communication to come to an amicable and constructive resolution as opposed to debiting my account on random days throughout the month. In the past I was able to make arrangements on the few occasions I defaulted and it is extremely unprofessional to behave in the manner that your institution has. highly frustrated. highly disgruntled. highly upset. I expect communication TODAY.
