Internet disconnects , *********** support teams , worst provider ever

Terrible service and support dont know what they are doing , I have opted in for a downgrade more then 2 months ago and they continue to charge me for the current line speed and cannot give me an answer to when it will be downgraded, first I was told I was the one that didnt do the downgrade , then it was sorry we dont know , and when my internet stops working at home support can never help, its a on going battle where I randomly get disconnected at home and no one can help! probably the worst internet provider I have had , will be changing to another provider
