Not a very reliable provider major issues my plan ...

Not a very reliable provider major issues my plan is 150mbps 15mbps upload speeds and lately been averaging way under the speeds range at around 10mbps. Trying to get my speeds back to normal range has been exhausting and basically been told to wait 2months for someone to "look into it" while still be charged FULL price for a sloppy service. NOT HAPPY AT ALL WITH THIS COMPANY WOULDN'T RECOMMEND TO MY FRIENDS
