Help with ultra slow, dial-up speed. Please.

Lately I've been having super slow speeds at home. At less than 1mb/s, I can't even watch Youtube on my phone. Online chat support doesn't exist. And the automated 800-number just sends a signal to reset the modem, which does nothing to improve the situation. Every time I try to call back, it just sends a reset signal again. I've reset all the hardware on my end several times as well. I'd love to speak with someone that could help me get close to 150mb speed I should have.
