Standard banks standard of service delivery is Zero!!!!

I have a standard bank connect simcard, the line has been suspended and I've spent more than 600 rand in airtime holding on the line and no one picks up. I've tried to pay it online but there's an error constantly. I've sent messages on the Facebook portal and I've been told someone is going to contact me, then they said they failed to make contact. I just haven't had any response, all I want is to pay for this account and have my line restored cos I run a business. At this point I feel like I would rather move my business account and personal account away from standard bank. Really frustrating!!!!
