Can't connect to company VPN on Hauwei B525 through Telkom LTE

The Telkom contact centre agents are only good at asking what your ID number is, the day your debit order goes off and other private questions - this goes on for a while after hanging on the line for at least 40 mins to get through. Then when you ask how to set up your new Hauwei B525 router to allow VPN traffic on your expensive LTE package they can't answer - the agent had never even heard of VPN! I was apparently the first customer to ask. Oh please help!
