Terrible service no follow up... problem still exists

If there was an option to rate zero stars I would... On the 24th of June I went to capitec bank at Ottery hyper in the western cape to change the debit order details of my final 3 payments of a loan I had for 3 years as I changed jobs and my new salary was actually going to be deposited into my capite account ( which on would think would make things simpler). The bank was offline at the time And the consultant was kind enough to get me on a call with someone who assisted me. I was assured that my other account would not be debited as I explained there would no longer be money in that account. It was still debited and luckily money was unexpectedly deposited into the account or I would have incurred bank charges. I didnt do anything about it as I assumed the changes would take effect in July. On the 17th of July I received an SMS and numerous smses in days to follow stating my loan account was in arrears. When I went into the bank the consultant was unable to pick up the deduction and said it might have been on my other account, I then printed a copy of that bank statement showing an abundance of funds on that date and no deductions attempted by capitec she then contacted someone who she explained this to and this person was adamant that the deduction was still from my different bank as she also could not pick it up even though the consultant was sitting with my bank statement. I then spoke to the consultant who was rude and irritated with me and asked why I was changing my debit order details as though I was attempting to get away from paying it. At the time I was trying to get car finance and this could negatively affect my credit record so I actually ended up transferring money to capitec and then paying the installment in the bank that day. I am still waiting on the call center manager to contact me as promised that day to fix the problem. Low and behold I just received another SMS from capitec stating that a deduction for the loan was just made on THE 14TH FOR A SECOND TIME. Who gets paid on the 14th? I luckily once again have double the loan installment in my account however my loan account shows arrears yet again even though the debit states successful. What the hell????? I am livid as that money was destined for my registration fees for the new semester due on the 18th. Penalties are charged on arrears amounts and I had a 2 year loan prior to this and have never ever missed a payment... I requested the recorded calls in the bank but I was not even contacted. I do give 5 stars to Naz at Capitec Ottery for going the extra mile to assist me and even contacted me to find out how she could further assist me a few days later. She is always very helpful and knows how to treat her customers and I can say that of the rest of the staff at that branch as well. Customer service or *****ver was contacted made a complete mess up and made no attempts to fix it or show the least bit of empathy.
