If you're having a good lane freeze, you don't need a gank. In fact, you're in a perfect spot, and it's the enemy jungler that has to show up or the enemy laner to play riskily to shove you in and reset the wave.
Actually, it's dangerous to gank. A good enemy jungler can wait for the countergank in the bush, they have a 2v2 with more minions, likely to double kill you and you lose out on a big wave and potentially fb tower.
Stop thinking the jungler has to gank you if your lane's freezed near you tower and it's the best thing he can do. It's not as simple as that. I don't get why you'd even be mad when you're in a perfect safe farming scenario. Freeze is basically the holy grail of toplane.
edit : if you're talking about midlane, idk. Kinda short lane, really hard and not that worth to freeze. There's still the countergank chance but less likely as it's usually more in the open
