Internet billing increase

I have called several times and have been waiting for someone to call me back in regards to the mistake that was made on my account. I called in to get a new modum. The gentleman that I spoke to talked me into getting more speed, Although my contract that I had for the year was not even up yet.  it's not up until April or may. I asked several times if the price was gonna go up, and I was told it was only gonna go up by $10 or $15 that it would still be under a $100. My bill is a $150 a month now for internet service. I am completely pissed off. I have been a customer for many years and I am so ready to walk away as your pricing is getting out of hand. Internet should not be $150 a month That is completely ridiculous.. Also was sent a little box for streaming and that was $15 a month which I didn't even ask for so I'm being built for something that I didn't even call in for. I do not appreciate items being added to my bill without my knowledge and I never received anything from this man that I was talking to on the phone about the price breakdown because if I would have seen the price breakdown. I would've never signed it and agreed to it. What I did get I signed but there was no prices on it. This is your customer service person's error that I am now having to pay for it's unacceptable. This matter needs to be addressed ASAP. I don't know if your reps get a commission for upselling but if that is the case then I got duped by your employee So that he could get a bigger commission.
