Vodacom data usage

Good day I have a Vodacom LTE contract (24 months which started in Feb 2019) with 100GB (50 anytime and 50GB night) and it lasts me between 10 and 14 days a month? Is this correct? I’ve tried to contact Vodacom several times and get nowhere. I’m so upset. I used to have a Telekom ADSL with 20GB a month and it always lasted the whole month. I am watching the exact amount of time and programs I used to watch via Telekom but now with Vodacom the 50GB anytime data is gone in 10 days. I also pay a lot more for the WiFi with Vodacom as opposed to what I paid at Telkom. Vodacom seems to gobble all the data up so quickly it’s frightening ?? I just wish I could cancel the contract with Vodacom and go back to Telkom. I’m so very very disappointed and angry with Vodacom and their customer service is useless. Very very upset as I trusted I would have enough data for a month. Disgraceful
