Unusable Telkom LTE

We app**** for the "uncapped" LTE contract where your speed is 10Mbps for 150Gig and if you reach your 150Gig you will be throttled to 4Mbps line for another 50Gig and then 2Mbps for rest of the month. Only problem is that you reach your "150Gig" you get very quick. We use android box to stream. We use over 2Gig in few minutes and according to me that is not right. If i make my phone a hotspot and use my data 1Gig lasts for over a week. So how does this work??Its like Telkom wants you to reach your cap ASAP so they can throttle you. And then i have another problem. Once you reach your 150Gig thats it. You supposed to go to 4Mbps but we get throttled to less than 1Mbps. Ive got screen shots i took where we even go as low as 200Kbps. And then when you phone telkom they ask you what you did to try and get better speed! So i need to sort it out myself???? Why do telkom employees get paid?? Im sure this is in breach of contract. You cant say we will be throttled to 4Mbps and then when we reach the "150Gig" we cant even use the internet. This happens every month. Not even to complain about when you phone telkom. You get cut off every 5 min. I tried one night 6 times to get the internet sorted but with no luck. Today is the 1st of the month.We didnt watch any tv because we had load shedding till 12:30. Switched tv on and we had a line of 300Kbps. This is the beginning of the month and already we dont even have 10Mbps line. And according to the app we have used 2Gig already. How is this possible as we didnt even use the internet. Can someone please sort this out or cancel this contract and ill get someone else that wont rip us off.
