Incompent Service Delivery

SR***..pathetic uc service from the get go! We have not had wifi for almost 2months.No one is calling! A month prior they had our numbers now they had incorrect numbers on the system! We had a big hick up prior to this, it was solved.. But now they are still billing my husband!! Come on!! How incompent can such a huge company be? There is no managers u can speak with, everytime its someone different.. And no one solves our issue.. Please let's just cancel this.. There are too many other competent businesses out there!
