Straight Talk complaint: Mobile Hotspot Data

Around the 27th or 28th my husband bought the $90 card for 2 phones, which he has done for several months now. On Mon. Nov 1st (morning) I attempted to use my Mobile Hotspot but it came up connected but no internet. Normally it says that only when I HAVE used all my mobile Hotspot data. Since yesterday afternoon (Tues Oct. 2) I click on mobile Hotspot, has me turn off wifi, then says please wait while verifying and then this comes up Mobile Hotspot (on top) and states your plan does not support mobile tethering I don’t even know what that is. It’s not showed this before when I would run out of Hotspot data but I have gotten really good about not running out of Mobile Hotspot data. Plus I learned to go to settings -connections-data usage which shows I have used 5.38gb of mobile data but if you scroll down to mobile data usage click on it scroll down to mobile Hotspot and tethering click on it and it shows me how much mobile Hotspot I have used which mine shows from Nov 1st to Nov 30th used 2.64gb and in oct 1 to oct 31st I had used 1.80gb . I have used this to help me not use up my mobile Hotspot quickly like I did in beginning when we 1st starting getting the $90 card. Also the card normally comes w 10gb hotspot but the new card has the word gold on it and we got 15 gb Hotspot. There is no way I used up that data that quickly. I may watch one maybe 2 movies the rest of time I’m surfing roku. So much to see. This has happened to me several times before, yes I called to find out what was going on each time it happened and I never got a true answer. And I never asked for a reimbursement of any kind until now.. my husband has no problem with his phone and we have same exact phone. We have had Straight Talk for 11yrs and this last year or two it has only gotten worse.and only my phone. My husband pays $90 a month for this service and he should get all that he has paid for but like I said it seems to only be my phone that this happens too.
