Bad Experience (horrific line speed and little assistance)

If I could give a negative star I would! For a whole month I have been on the phone with them and in the client portal to get my line speed up to standard or even just functioning. 90% of the time my line was either non-existent or running at 30% of the speed I am paying for. When asking what the problem is and how to remedy the reply is simply settings have been adjusted please test again. This cycle continued for 30 days straight! Never have I struggled with an ISP this much! They started off by double deducting payments to add to the frustration!
