NOT GETTING SPEED PAYING FOR.
Hello, I just upgraded my internet from 150 Mbps to 250 Mbps. Now after upgrading, I did a speed test and got 30 Mbps. so I called and the women told me my modem isn't high-speed modem and would have to rent one from them. that is completely untrue. I have an arris sb6190. Now after thinking about this overnight, it has come to my attention that all this time I paying for 150 Mbps I never received more than 75 Mbps and obviously now I am paying for 250 Mbps and the same thing is happening. Does anyone know what I can do?
