Poor Service -New Business Account Online Application

I app**** with FNB for new business account online on the 9th Sept 2022. Submitted all documents that were required, after I was promised to get a follow-up email in 3 working days with bank documents to be completed and send back for account activation, I waited until 15th Sept 2022 to receive documents. I completed them signed and send back on the 16th Sept 2022. Since then, I have not heard from FNB. Today, the 23th Sept 2022 I went to the nearest branch I was connected telephonicaly with Business Account department, a person called Nelson answered and referred the call to the lady by the name of Bianca. After she did all verifications, she told me the matter will be escalated, I then asked for her superior because of the turnaround time has lapsed since the application date. Unfortunately, there no Team Leaders or senior management to attend the matter but to wait until my query is first online only then I will be attended to. This is very disappointing situation I have a business deal that I am about to loose because the company cannot provide confirmation letter from the bank. Online services is very poor and with this quality of services it's really not a healthy business relationship.
