Very bad customer service

I've just had the worst experience when doing an online application. Had to call numerous times to follow up, but no satisfaction and the sales department did not call me back after a number of escalations. Complaints department consultant(Mbali) did very well in keeping me posted, but the stakeholder responsible to keep me posted didn't give her any concrete facts to give me as the customer or a time line to when the matter will be resolved. I've submitted a similar application at FNB a few months and it got sorted within 3 days. Standard bank online sales took 5 days to respond. After spoken to consultant she advised that matter will be resolved within 24 hours, which translates into 3 business days. After 4 business days still no response from sales or any feedback to complaints regarding a resolution. Matter escalated for the 4th time for resolution. And the wait continues...
