Price increase is DOUBLE MY RATE?

I woke up this morning to see my automatic payment pull for my 500mbps speed plan, usually $59.99/mo jump today to $105.99/mo. I went to check my plan and ALL the available plans have almost doubled in price to me. All I can find is a general FAQ about price increases talking about “investments” the company is making. Even if I go down to the SLOWEST option available, it is still MORE EXPENSIVE than the plan I had. No promotions were part of my plan. Can someone walk me through what made it necessary to double the cost of my internet? Not to mention I was not notified of this change happening at ALL prior. If I cannot get this figured out, I will be switching providers.
