Back end office messing up my RCS application, Please sort this mess ASAP

I app**** for a loan a revolving loan at standard bank on the 06/01/2023 and visited the branch the next day to finalize my application with them with supporting documents. My salary is paid to their account and I also have a credit card facility with them. upon completion of the application everything went through only thing outstanding was confirmation of employment ( this was however not done at all). When i follow up back office is referring to the branch as per their records it states something about investigation ( nothing is being explained about it either). As it stands Im loosing deposit for the vehicle, unable to get credit with other service providers as my credit score has been negatively affected by Standard bank. I am disgusted by this kind of service and unexplained scrutiny every-time i deal with the bank. If the application did not go through in the beginning I would not have put deposit on the vehicle i intended to purchase. The branch assisted me perfectly I have no complain - Your back office did not do what they are suppose to do hence i am in this problem. I need answers ASAP - Devon Alexander from your back office might explain this better hence he is not giving me satisfactory answers. How does one ask for information that is already loaded on the system?
