Help with 3 pole switch wiring

i replaced several 3 way switches in my living area with 2 pole switches....because I'm not an electrician and didn't know there was a difference. After learning of my mistake, I replaced the 2 pole switches with new 3 way switches, however, now the wires to two pair of the switches aren't receiving power. On wall A is a 3 switch panel, with switches that control the hall light, ceiling fan, and fan light. The hall switch functions properly, but there is no power to the other two switches. On wall B is a 3 switch panel, with switches that control the fan, fan light, and kitchen light. None of these switches have power. On wall C is a 4 switch panel, with switches that control the garage light, one that controls unknown/nothing, the kitchen light, and the dining room light. The garage is 2 pole and works properly. The dining room works properly. The kitchen switch has no power. So, the ceiling fan and light, and the kitchen light switches aren't receiving power, and the breaker is on. I need help please.
