Horribly SLA and business workflow

Horrible workload and SLA, opened a business account about 3 weeks back. Received my card via courier few days after opening the account( joined business account) tell me why up until today we haven't been able to active the business banking app? Last time I was at the branch I was told someone from call center will call me to assist to set it up as at the branch they don't do business banking app profiles,a week passed and went back again yesterday and only yesterday another lady at the branch informed another that she needs to escalate the request to a specialist who will call us and assist. It has been over 24 hours since she put in the "escalation request" 1 think I can commend is the security on the account, top notch but it is a HUGE inconvenience to me at the moment as I can not view the balance on the account or the statement because apparently according to FNB it can only be viewed from the banking app, which at the moment I don't have, there is money being deposited into that account every week since it has been opened but I can not transact or check the balance, what is the SLA on this? What is the workflow after opening a business account.? We have ba d experience already from the bank and we haven't even started doing business with them,to my understanding escalation should have 24 hour SLA not more but here I am still waiting for the specialist to call me back,I followed up yesterday before going to the branch and called them, I went as far as to tell the girl I was speaking with to call me if my life drops, and guess what? It dropped as she was busy checking on her side and she never gotten back to me. Ridiculous I tell you
