Unable to get help from Vodacom

Before deciding to take out an LTE data contract with a router, I asked the lady numerous times are you sure it's uncapped, she reassured me it was. The data would stream at normal speed, after the bundle is up the speed would drop. Now my parents are sitting without internet and NO ONE at Vodacom is willing to help?!! Why do you pay for no service????? After numerous attempts to speak to a PERSON over the phone, I went into Greenstone Vodacom, all the guy said was sorry there is no such thing as uncapped LTE. Not willing to check or help. Such a big issue to do your job apparently! I don't understand why you pay for a service, yet when you need them to sort things out they never want to help you? You can increase randomly after only a few months of getting a contract. Pathetic service once again from Vodacom.
