Hotspot Data Question

I have two accounts, the first being the Go5G Plus 55 and the second is the 5G Mobile Internet w/100GB high-speed data. The first plan includes 50GB of hotspot data and the second I thought included 100GB as shown in the title. When I purchased those plans at the local T-Mobile store the sales person assured me that I would get a total of 150GB of high-speed hotspot data per month. However, I have had these plans for several months and have yet to get beyond 100GB of data usage per month without being severely throttled. Was I mislead about the total high-speed data or am I paying for 50GB of data per month that I am not receiving?
