Bad service

I have been using this network for years , but service that I received this week was disgusting, I bought a 1Gb data on Monday and it was not allocated, i called vodacom I spoke to Juliet and she said the had a network problem I must wait for 24 hours. A day 2 days passed still there was nothing until I called again on Wednesday and I spoke to someone else and he helped me . Vodacom gave me 2Gb more but I tell u it is running out like hot cakes , just imagine the inconvenience they caused me and my business now they are eating their data like nothing. How can I use 2Gb in 2 days because I'm also using Wi-Fi for my business I don't if I want to use vodacom again
