Highly frustrated, day 3 and they cannot get my internet to work . They not getting back to me and I have been making phone calls as to no luck . Terrible service from Ethan ,seems he does not value customers . I work from home and have been inconvenienced for 3 days now , they lines also don't work after working hours but they will tell you their lines operate after working hours ...I would like their owner to contact me coz nothing is being done Abt my situation.
