I hate to tell you this but all carriers are having issues with overload. Some areas are better than others but until the carriers convert a lot of infrastructure to the upgraded transport this will continue in some areas. As for the speed to upgrade or repair, any business will do an extensive investigation to avoid these issues. I donít know what type of business your in or work for but ATT, Tmobile, Verizon and other spend billions to do upgrades. When you get the number of problems you seem to have it's always best to ask for a manager and avoid the script responses.
