FNB dont respond

My son in law tried to open a bank account for his son. after a month he gave up. I have been trying to open and account for my grandson and 2 weeks later nothing. I get emails which say they will contact me in 24 to 48 hours. (obviously they don't work so they look at 48 hours) when 48 hours have passed they close the file. I have had 2 missed calls, it rings twice and they put down. the service cannot be called shocking as there is no service from FNB.
