fnb treats business clients badly

I have had the worst exsperience with FNB bank , and all I wanted was just to open a gold cheque business account online and I am still waiting for almost 3 weeks now and I send emails and call and get no response , this is pathetic service for a bank of this calliper and especially to treat business clients like this is bad for business , to top it all up the branch in vangate couldn't even help me properly and they also don't have a business consultant which other banks have , so if this is the service I get to open a sccount , I am very scared to what service I will get when enquiring on my account when open
