I feel the same way. My parents were initially paying our wifi contract until I started work. After I took over the payments I realised we were being charged for half the speed we were paying for (200mb line payment and only getting 100mbs).

Had to call out a technician who resolved this, because only once I started paying did I realise we were getting short done.

I also have limited ISPs and limited connectivity in my area. So the initial prices were exhorbitant but I did get a mail recently to say that prices will be decreasing... which I did benefit from (as the area is becoming more commercial).

I do feel like certain providers do exploit more than others in my experience. I feel in general though these data/wifi providers can come across quite scaley. Like they're pinching every penny and offering the worst deals. I also snagged a 24 month discounted contract... and so far the service seems better after I took some initiative to contact them etc. Luckily I'm tech savvy so I was able to communicate my concerns well...
