The number above gives three choices to participate in various programs, then cuts off. How can anyone communicate with you????
I am trying to contact to apply for a job. Do you have a jobs and careers phone number, or can I submit my job application online?
I have not have a phone for over a week, there is something wrong with my line. Twice I was told MCI will send a technician, on 2 different days, but they never did and I waited for nothing! It is a disgrace how you treat long time customers like myself. I am in El Paso, TX. Account: 5F195707, phone: 915-351-2309.
I feel like switching phone services to another more professional, serious company!
i keep e=mailing that my phone doesn’t work when it storms . it is either dead or i get static and can’t use it.
this is one of the most unprofessional unorganized work from home companies I have ever seen in my life they send you equipment that dont work the trainers are rude i literally would not recommend this company to anybody to work for they lied and said the training was two weeks come to find out its three days
