I own a ballroom dance studio and I get calls from students to schedule their appointments. I got cingular service to be able to take my students call from my students anytime anywhere; since almost a month Cingular service has been poor and dropping calls. My current students are very unhappy and new ones can't understand what I am saying; so I end up losing them. Cingular customer representatives are not very helpful and not correcting the problem. I am in a contract.; feel trapped and feel that Cingular don't have any respect for their customers. What to do!
