Poor customer service from old mutaul

I am writing this complain with a huge dissapointment with Old mMartial, I did not think I would experience very poor service with such a big company that promises exceptional customer service. . I decided to open an educational with plan for my son , an was assisted by a financial adviser named Nkuli to open one, first debit was debited on the wrong that of which i requested to be debited last day of the month, this could have cost me money had the transaction bounced. I experienced this again this month after Nkuli the financial adviser promised me that this is fixed. This is not professional. I need the money to be returned because I was supposed to use the money for petrol , since I was aware that the money will be debited when my salary hits my account. The most annoying part is the when I spoke to Nkuli she responded by telling me that she does not have control over the system what king of customer service is this. I really did not expect the kind of response because she's the one who facilitated the whole process , now she telling she does not have control and that i should go to the branch, the question is at whose expense must I go to the branch?
